Eh Steve! (I couldn't resist). But in all seriousness, I tend to blurt out alot of random old pop-culture quotes that are relevant, for instance, whenever I figure something out, I tend to yell "Zaloom" to the greeting of puzzled looks. Whenever I get ticked off about something, I just start muttering in some kind of made up Yiddish type language (Hoif Macgoif, Oh masheeshkaboff). I tend to give a snappy "What's it to you" to anyone on my back about something (Which luckily is a rare occurence). I often say "Neat!" when somethings, well, generally awe-inspiring.
