I've touched on this before but Dave is one of those one note shit heads who think acting like a retard while playing a game to be as annoying as possible is "funny" and that's why he'll always be a mid guest at best. He's only been entertaining when telling stories and the AI videos he was in used the same jokes over and over which again is his entire low IQ manchild sense of humor on display.
The Oneyplays guest tier list is and always will be.
S: Ding Dong & Julian (Ding dong alone has made Chris laugh and act goofy more consistently than anyone else in OP history, GOAT.), Cory, Zach.
A: Tomar.
B: Lyle. Dave. Harry.
C: Matt Twatson.(but fuck that two faced asshole in general)
D: Adam.
E: The one offs.
