Why not consider PZ Myers a comedian in general? Here's his "Why there has been an increase of female speakers at TAM" joke:
"Need I point out that the reason gender ratios have been improving is because people like Ophelia and Rebecca Watson and Greta Christina and Jen McCreight have been pointing out the discrimination for years."
Denying that the increase was due to DJ Grothe's programming. Hilarious! Or this one:
"For years, I’ve been saying that the way to make conferences and the movement as a whole less biased towards male concerns is to ask women what matters to them, and to listen and respond, rather than telling the little ladies what they need to hear."
Yet in the same article, as the punch line, he scolds Harriet Hall for expressing what matters to her and tells her what she needs to hear.
He pulled of these and more jokes in just one article:
