    You don’t even do a flip turn with the butterfly and you did a breaststroke kick and flip turned but when you do I utter fly you grab the edge and do an open turn

    I used to be on a swim team and my sister still is and it was so painful to watch this video. Ethan doing breaststroke kick with butterfly stroke, his butterfly in general, the fact that neither of them were wearing their swim caps properly, it was a recipe for disaster.

    As a competitive swimmer for over 10 years, this pains me in my soul. My strokes were butterfly and breaststroke too, went to states for them in high school.

    My dad taught me to swim with the helpful phrase, "Breathe the air, not the water." Thanks, Dad. I don't know what I would have done if you had not imparted such knowledge upon me.

    Pool people made up the myth that you can't eat for 30min before swimming cuz they didn't want people getting food in their pools

    i think it's nice that Mark gets to be a big kid in a way, since he's said in the past he had a rough childhood. He certainly worked hard enough to get here. I'm really going to miss this channel when it's gone. The Ethan/Mark combo just works comedically. Not as well as Jacksepticeye and Mark but still really funny.

    I think Mark's butterfly stoke is better than Ethan's.

    I have been told by multiple people including my very smart uncle that you can eat before going in the water but you cant drink. I dont know why I know this, I just do.

    I get that this editor is trying to be all "a e s t h e t i c" with the 80s instructional video thing, but anyone else find it incredibly annoying and obnoxious?

  • Cherry

    this is the exact opposite energy from the mermaid video

    Fun fact: it doesn’t matter if ya eat before you go in a pool or wait 30 minutes before, swallowing water while swimming WILL cause you to vomit

    I mean, everyone was terrefied of the sea after wittnessing jaws


    My favorite part about the entire f****** video is that Ethan has no idea how to talk

  • Forwardstory

    i feel like mark and ethan are going to commit suicide for the finale of unus annus because this seems like bucket-list type stuff and "memento mori" is a symbol relating to the inevitability of death
