Did you see that fuckin Seaborg bump into me on the street the other day?

I saw Mark take his shirt off in gym class yesterday... he had to be the biggest Seaborg i've ever seen.

That god damn seaborg keeps rubbing up on my leg on the dance floor.

Don't you hate it when a seaborg comes into your room and explodes your pop all over your carpet?
