Nick wouldn't be a bad looking guy if he'd only do something about his Bert Syndrome. Can't he get it waxed or threaded or something?

Ernie and Bert Syndrome 

Ernie and Bert Syndrome is the rare case of when two men declare homosexuality and get into a relationship with each other, but also declare asexuality, effectively making them just friends.

"Tim and Jerry are gay but they both said they're asexual."
"So that makes them just friends then. There's a term for that. Its called Ernie and Bert Syndrome."
