The Donkeys try to flex their mental muscles for once by taking on Sam's challenge: build an airplane using a fence and a bathtub, and do it before anyone loses his mind completely. Can Sam teach his friends the intricacies of Garry's Mod. Can they actually figure out what's going on. Does Jolo have anything better to do than shoot everyone. Garry's Mod is a sandbox physics game built on the Source engine. There are no predetermined objectives: each game is limited only by the players' creativity and understanding of the laws of physics. Also by their intelligence. There is no real way to win - but in this case, the Donkeypits sure know what it means to lose. New videos every Saturday. Subscribe for updates and other funny stuff.
