That's not an antenna.

Conversation between myself and a student at lunch:

"So guys, I saw this movie and there was this guy and he was NAKED! He wasn't even wearing underpants-"
"Umm! Is that something you should be talking about at school?"
"Well, no... but it's really funny!"
*Shaking of my head*
He wanders away, continuing the story under his breath (guess he just had to get it out) "And then he said... boy, that sure is a funny place for an antenna!"

What on Earth was that boy watching!? Although, it was one of those DON'T LAUGH, DO. NOT. LAUGH. moments!
