Why yes, I was on tv.

In the theater, after seeing the Indiana Jones Epic Stunt Spectacular at Studios:

Random man: Excuse me, did you do American Idol?

Me, thinking he meant the American Idol Experience attraction: No, I'm just a regular park-goer...

Random man: Oh, my son thought you were a famous American Idol from TV. Sorry!

Me: ............

That's pretty cool. If I thought a little bit faster, the conversation should have gone like this:

Random man: Excuse me, did you do American Idol?

Me: Why yes, sir! I was on with that guy with the hair. Would you like an autograph?

It's just like Winston says in Ghostbusters: "Ray, when someone asks you if you're a god, you say 'YES'!"
