haha Me and my pal do a, um... version of this! :)

"Funny" might be not the right term, but it's a really interesting video.
World Science Festival 2009: Bobby McFerrin Demonstrates the Power of the Pentatonic Scale

Freeman's mind! See inside the head of Gordon Freeman, physicist and neurotic individual. There's 13-14 episodes so far, and updates come every few weeks.

Freeman's mind is so cool, i hope for new episodes soon

I have no idea what kind of show is that but yesterday during my workout I almost fell off my treadmill because I was laughing so hard.

I'm necro'ing this place, for this blew me away:

Okay, the video isn't that great (the main part of the action is hard to see), but the event itself is pretty funny:

Germany, 5th tier soccer league, important match. Black team shoots the ball towards the empty goal. A substitute of the white team, who happens to stand next to the goal while he's warming up and preparing for a possible substitution, steps onto the pitch and kicks the ball away before it enters the goal. Referee sends the player off (although he technically hasn't been "in" the game yet ;) ). Bit of chaos on the pitch afterwards. Not caught on the video: Game continues with a throwdown (the referee can't award a goal that hasn't been taken), but the white team decides to not support the unsportsmanlike action of their substitute. They don't participate in the throwdown and let the black team score a goal.

Sorry again that the video doesn't convey the hilarity of the situation all that well ... but everyone who played soccer at least once should be able to feel the collective "WTF" feeling on the pitch and on the stands. ;)
