Gabe and Tycho, those brilliantly foul-mouthed chuckleheads capture the unique and wonderful ride of the amazingly original game of Portal (found in The Orange Box).

Portal's a game where you navigate through an inventive, dangerous and challenging environment armed with only a tool that creates portals in the universe. you slide through the portal and end up somewhere else.

It's not as random as it sounds, it's a refreshing change from most point and click games where you position the cursor over the thing you want to make dead.

This Tshirt captures the fun and uniqueness of the game as only the guys at Penny Arcade can. (via Penny Arcade)
