    If down thumbed this video, you are a Russian bot.

  2. patrick schneer

    I can’t believe you were only on the ship for a day, it seemed like you were there for a week or more

  3. David McClellan

    The smile on Destin's face just firing the 50 made my day!

  4. Shinokami007

    couldn't write "DEFECATE" in the title or what? why do we use that strange onomatopoeia move instead of the smarter word ahahha :) anyway thanks for the video <3

  5. USS Long Island [CVE-1]

    Dont worry guys, if it were a german submarine, he wouls have flooded the entire craft.


    confirmed: A golfball is deadlier than a gun ;-;

  7. Taha Meron

    Nice video. You should wash you hands after going to the bathroom :P

  8. evergreen2y

    I reckon a submarine is like a under water hogwarts.

  9. Hunter Deem

    His screams remind me of the screams from Broforce

  10. ASAWProductions

    Big props for respecting the privacy of the injured person.

  11. Bubblezov Love

    I really can't imagine a more respectable person than Destin. Just based on all his videos I feel huge respect for him. I would LOVE to spend a day on the farm with Destin, just talking about stuff and helping wherever he needed... I feel very lucky to have met at least one person I would put at the same level as Destin. 😎 The words *role model * is so apt....

    I think there's a bias in favor of the left-side. To really test that out, you'd need to switch lines between whackers each match and see the results.

  16. Louie Uriostequi

    Dude stop stfu you’re getting annoying explaining

  17. Bubblezov Love

    I'd like to see mental health covered. I mean I know they're soldiers but in an environment like that they must at least think about strongly keeping people focussed and ok....

  18. Louie Uriostequi

    We are not slow and stupid like you and other people I can perfectly understand the soldier, you’re just making everything sound so difficult to understand

    Ok I have never heard of 'code switching' but now that I do, I finally realize there's a term for what I used to do a lot while younger, but I hated myself so much for it even though it wasn't a 'conscious' effort to do it. I always felt it was just a subconscious way i was trying to fit in with others. But I've always tried to stop myself doing it as I got older and realized I was doing it, sometimes apologizing to the people to do it. Normally it would be various accents around me like Hispanic, a bit "ghetto" (if you can call that an accent), etc. but it all came to a head when someone from North Carolina visited me, and OMG I just couldn't stop with the "twang" in my voice to the point where they said it was annoying (for point of reference from California), then I realized I was doing it without realizing it.

  26. Moto Nugget

    This series is awesome! Thank you for the videos!

  27. Simon Andrews

    15:18 you can just tell there's some lawyer/health and safety person in the background shaking their head.

  28. AntiCitizenX

    "Learn from that what you will." --- Nice way of saying you have no idea how to interpret it. :)

  29. Apolo

    So Usually I eat while watching these videos. Now im just confused on what to do... Thanks for producing high quality videos as always, hope you feel proud of yourself

    Did you capitalize the SUB part of subscribe as some kind of a submarine pun? If you did, I loved it! hahaha

  43. Vincent Chan

    I am surprised that a military sub actually got an extra bed for "guest".

  44. Naz

    ahaha I had so much fun watching this!

    8:42 Expected ring tone for waking up on a submarine


    Add to everything else the fact that the ship might roll and spill your pots, this kitchen is straight out of Overcooked.

    Can't believe they don't have a more efficient shower heads. They mustn't have pop up ads down there.

    My wife and I play cribbage at least once every day.

    At 10:58 they noticed a mistake but everything was ok untill 8:39 . That was the first time that someone moved correctly placed pieces to a wrong place on the grid. At 8:02 you can still see them correctly placed on the grid.

  57. William Popowitch

    Thanks Destin! I was actually just about to do that.

  58. Andre Rahming

    I’m watching this while pooping.

  59. Titanium Mechanism

    I bet that Shell didn't sponsor them out of the goodness of their heart, but whatever motivation they had, it resulted in something great.

  60. GreatFlamin Zeus

    6:48 uuhhh, what’s the “Bug Juice” container? Or is that classified?

  61. Camecol21

    Destin, Thank you for asking excellent questions and making the most of a one-night stay.

  63. Raymond Bosman

    You need to tell your friends at Raycon to send to Australia!

  64. Camecol21

    Yeoman = S1 on the sub.

  65. BadKarma 714

    I have a question what is a firing solution Did they put in the torpedo tubes? Is it the water

  66. Adam Kaufman

    Maybe the "hair" is a scale that is still growing and will later sort of unroll into the right shape!

  76. Oakstrom

    Loved this series. As a former Nuclear Electrician's Mate, it was a shame that you couldn't see the Engineering and Maneuvering spaces. The Nukes control the Rx to make the steam, water, electricity, and propulsion. They're a good bunch and live an especially tough life on board a submarine.

  77. MisfitActual

    6:45 your welcome

    So why doesn't the ball knuckle?

    “Just a cluster of cells with no value” “can’t even think so not important” I can’t believe that people can see the miracle of life especially in their own race and just dismiss it because it’s inconvenient for them

  80. Squid Gert

    I’m claustrophobic just watching it…
