OOPS - did I do that?

First time I played online cash game, I sat down with my whole bankroll at a cash game (which I had no experience in) and accidentally hit the call button with J2off after two players went all-in before me with AA and QQ. Flopped J22 and tripled up. Left the table immediately out of embarrassment. Any other crazy mis-click stories?

I've done that before - no specific situation comes to mind, but I've accidentally gone all-in, got called, and pulled off a miserable suck-out. Also the other way - mis-clicked all-in and lost. In my case, it comes from multitasking, and having the mouse in the wrong place when the window pops up.
