    Mark: This is gonna be a fun year Ethan: *insert I'm in danger meme here*

  2. David Walsh

    Man, Ethan is such a pussy

  3. JustAlpha

    The paintball gun is a Tippmann Cronus for any of you wondering. I've modified mine extensively (yeah, I am giving myself pride for it, I'll admit it! Hehehe), so that's how I was able to tell. Also it's shape.

  7. Nikooo

    "Death is always watching... and in this case, it has a paint gun" I love this so much


    @2:12 - No...youtube started in 2005.

  9. ShadesMcF

    _Looks like we got something to look forward to folks_ Death is inevitable. It can be scary. Since we never will know when it comes or how it will feel like. I knew Ethan is gonna get hurt again at some point. Least we now know how. Theres a paint ball with his name on it. Shouldn't have chickened out. Its like he read an older comment about him getting hurt the next time and try to avoid it, but only made it worse.

    You see what's crazy is that every time this channel uploads the intro is just a ticking timer that's counting down day by day to the inevitable doom that this channel is going to be deleted.......

    I really hope Ethan gets his one totally randomly and when he least expects it... like in the middle of a totally different episode, without any explanation and completely by surprise 😈

  42. Trasher

    Ethan hasn't learned that actions have consequences... This is gonna be fun to see unfold.
