I love physics humor. Here is a wonderful example from The Arrogance of Physics, a poem by John Koethe, distinguished professor of philosophy at the University of Wisconsin-Milwaukee.

As your twin ages, while you remain perpetually young --
Though a lot of good it does you, existing as you do
At no place in particular, smeared out everywhere
Until someone sees you and your wave packet collapses.
