Let's see if I can recall this... (from jokes with Einstien)
Kid: Hey, I gotta joke! What do you call the ratio of the circumference of a jack-o-lanter to it's diameter?
Einstien: Pumpkin pi.
Kid: Oh, yeah... that's right.
Einstien: It's not funny.
Kid: It's not? I thought it was kinda cute...
Einstien: It's not.
