Roosterteeth 

True veterans of the machinima field, Roosterteeth are the creative geniuses who created the fularious web-series Red VS Blue (based off the Halo series), as well as Strangerhood (based off the Sims). Unlike many fan-based creations, Roosterteeth haven't shown any signs of slowing down over the years; to this day, they continue to roll out hilarious comedy that gives them their well-deserved reputation for being comedy geniuses. They're also credited for producing the brief P.A.N.I.C.S series ("People Acting Normal in Crazyass Situations"), for the F.E.A.R game; and while PANICS was only brief, it did deliver a good laugh. However, Roosterteeth have forever remained most famous for their work in Red VS Blue, which continues to be widely regarded as one of the funniest things on the Internet.

Church (Red VS Blue): "Tucker, there's a very fine line between not listening and not caring. I like to think I walk that line everyday of my life."

Peeing at a toilet (usually urinals) when your pee splashes and goes right into your mouth or on your lips.
