I'm generally the player who's character sheet has to be checked repeatedly. Of course, that's because I tend to be so detailed to explain everything that the DMs tend to forget the important stuff for any given situation.

I can't count the number of times a DM has said to me, "I forgot you could do that."

Hey - it's not my fault, that my character is really good at avoiding hits...
Well maybe it is...

But at least I am the pacifist in our group - all enemies survive - they are just unconscious when I am done...

Nothing said's 'trooper canon fodder' like 'Skittle solderers'. lol

I was helping a Gm beta test a system that he was developing where you could combine skills to increase the amount of dice. Most characters at lvl 1 would roll about 3d6.

My character's first attack was 7d6. I was promptly asked to hand over, explain, and then the GM spent the next three weeks trying to unbreak my character, with only slight success.

Good times, good times.

I know a guy who's fond of monks with heavy armor, the GM has just given up on trying to un-snaggle that mess and just bans him from playing infinite dodging super-armor fisticuffs man anymore.

I once played a character named "Infinite Dodging Super-Armor Fisticuffs Man". It was a Magitek based superhero campaign (PCs got infused with a super serum that gave them great physical or magical powers).

My character threw lightning. It's amazing how effective an overblown yet misleading name is in getting surprise rounds.
