I was playing Jackie Chan's Action Kung Fu for the NES on an emulator a few years ago (yeah this was the time before I went and bought out every NES game I'd ever played when I was younger) and I was rather frustrated.

Keep in mind Action Kung Fu isn't a particularly frustrating game until you reach the last boss, who is to put it quite bluntly, a bastard.

I'd been rather upset that I was back in the first level, and I had reached this part where the screen scrolls classic Super Mario Brothers 3 Koopaling airship style.

I died somewhere in the middle of the level. Well when Jackie Chan dies in the game, he does this sort of weird little kick in the air with his leg while he's lying on the floor dead. I was so pissed off that I decided to mock that kick by doing it from my chair. Well I forgot to move the chair back, and I kicked the keyboard to the floor.
