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.
Link to video 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. ;)
