A Puns-ential Crisis

Why did the existentialist break up with his girlfriend?

Or maybe the answer is, "Because he was in a existentialist relationship, it was a 'to be' or not to be' situation."

On a related note, what do you call a philosopher who's always making jokes?

An existenial comedian.

But wait, what about the meaning of life?

Is it to find the meaning, or is it just to pun-derstand it?
