Mitty, hahaha, I'm sitting here naked picking my nose blinking continously while reading your list, my mouth is agape, drooling all over the keyboard, and oops I just belched so loudly the cat attacked me.
No I don't have any annoying habits to list sorry.
ps. oh yes I crack my knuckles sometimes.
pps. My cat has a bad habit of farting when you least expect it, one of those silent farts that creep up on you and has you leaping towards the door to escape the stench, and the cat just sits there looking around wondering why the room is empty all of a sudden.
