I spend a lot of time working with comedy and theater groups, and I like looking for the humor in everything, especially myself. If I can't find my own faults to be humorous, then who can?. Though I do act and do a bit of improv, I prefer to stay behind the scenes and work on the technical side of things.
At the moment I'm using "Huzzah!" as my personal catchphrase whenever I'm happy about or celebrating something. It's at the point where several of my friends have picked it up, so that every round of applause is followed by a hearty chorus of "huzzahs." I get endless joy out of this for some reason.
