I suffer from this problem -all- the time.
I have the urge to behave in the most ridiculous manner possible, both OOCly and ICly while in-game, at least once when logging into the game at any given time.
Stepping up to any random PC and telling them what my character's stats are, OOCly, exactly as they are written in the "score".
I.e. tell elf MY STRENGTH IS GOOD, MY AGILITY IS ABSOLUTELY INCREDIBLE, MY WiSDOM IS BELOW AVERAGE, MY ENDURANCE IS GOOD.
Emoting something completely unfeasible to describe the result of a coded action.
I.e. Walking down the street and sayng hi to someone in a casually public place, and then:
emote grabs his hunk of erdlu meat with both hands, his eyes glowing red as the meat begins to bubble and blister, flames suddenly erupting from the blackened flesh.
craft meat into roasted erdlu breast
Subduing someone you're having a casual conversation with, and then continuing to RP as though nothing has happened.
i.e. say How is Trali doing these days?
say I haven't seen her in a while.
It just never ends.
