YOU'RE MOM.
A weeping Willow.
He was a little down.
Your mom can fit 3 people inside her comfortably!
Not nearly as long as it would take to travel around your mom.
One's a Swedish Phish and the other's a fetus swish
A baby in two dumpsters.
3, duh. (My ex's 9 year old little sister told me this joke, and followed is up with: "and YOU'RE the math guy!" >< Burned.)
