Ever hit the wrong button?

So unbelievably true that I hate to write this post. Playing $10/20, I worked a $1100 starting stack to $4500. Played just great. Really really solid. Then, just now, I was involved in a pot that went as follows:

From the BB, I called a raise of $70 from the big stack at the table with AJs. He had been pushing people around, raising about 30-40% of the pots, so I figure I'm ahead. Flop comes QJ2. I went to make a pot-size lead-out bet of $150, just to see where I was. Instead, my cursor wandered over to "max" instead of "pot" and I automatically hit "enter" after clicking the wrong button. So, here I sit with $4400 bet into a $150 pot. The guy sits there, ponders what the f&*$£ck this guys is doing and thinks for 20 seconds before calling me with QQ, having hit his nut set. I HAVE NEVER DONE THAT BEFORE and the one time I do it, the guy has hit the NUTS. SO SICK. It is so stupid, I can't even get mad. Please, someone tell me you've done this before.

I think God is telling me something....give it up son!
