So, for my church Halloween party, I decided to be a Monty Python character, namely, a Gumby:
I thought this would be really fun. Maybe I'd even stay in character for the whole party. I might walk up the bishop and say, "ARE... YOU... THE... BISHOP? MY... SPIRIT... HURTS," or something like that. There was only one problem: nobody at the party knew what the hell a Gumby was.
Typical conversation (repeated several times):
"What are you?"
"I'm a Gumby."
"It's a Monty Python character."
"Oh. Which movie was he in?"
"They were actually in the TV show."
"Oh. Monty Python had a TV show?"
I've learned a valuable lesson: Don't wear a costume so cool that nobody at the party knows what the hell you are. Either that, or start going to cooler parties.
