Computer comedy is when you're entering "vi" commands into Microsoft Notepad. Kinda makes you feel silly. 
You only do that in Microsoft Notepad?
I have done it in Unix prompts (not really as bad since it blends with history, but it wasn't the reason I was doing it...), DOS-like Command prompts on Windows, HP3k MPE/iX and it's shell, too.
My boss used to have 2 keyboards in front of him (1 for PC, while other was a dumb terminal) - he would type on the wrong one and get frustrated because he was looking at the other screen. I thought... how silly... then later found myself doing the same thing. Multiple keyboards is definitely and old time handicap...
