No, I won't inflict any mathematician/engineer/scientist jokes on you. (Not that I couldn't ....) I've been reminded recently of some good science humor cartooning.
Online, you might enjoy:
A science cartoonist I've enjoyed for years and recently reread his collections Einstein Simplified and Einstein Atomized is Sidney Harris. You can get an online taste here.
And, though it was never really a science cartoon, Gary Larson's Far Side is a favorite of mine, and was quite popular among scientists.
