Puns, Jokes and Poems

1)

I know some of my jokes and puns are lame, but here goes nothing:

I guess if someone laughs at you for having stuff stuck in between your teeth, you just gotta brush it off...

There, my first pun, now my joke:

Why did the guy take so long in the washroom?
I guess he fell asleep in the RESTroom.

They are lame, so don't judge me :3
