Random people, celebrities of note come to your shows over the years, and I've had some really strange ones. Like the guy from Kiss. Gene Simmons has literally been in the audience at my shows, like, four times. I don't know if he knows me; he's just a big fan of comedy.
I listened to this interview once with Jerry Seinfeld that really influenced my comedy and all of my writing, which is that when you're starting out in comedy, it's the audience that tells you what's funny about you. And you need to listen to that and make a note of that.
