Nuts

"Maybe I'm The One Who's Nuts" is a song sung by Marceline in "I Remember You"

Lyrics
You’re so annoying you pitiful old man.

I’d like to help you but I don’t know if I can.

I thought you were nuts.

But you’re really, really, really not.

Every time I move eventually you find me and start hanging around.

Just another lame excuse to see me man it’s getting me down.

You know I’m actually glad to see you.

Maybe I’m the one who’s (sighs) nuts.
