How the gentlemen died out

I swear that third one is my brother, it even has his tail.

Hung around too many girls in the gonads. Kibitzing slowed them down and the slow but sure of the mission girls got the prize. Haha.

Sexist

Uh. Too bad, the said gentlemen were actual the conniving of the lot. The first sperms to get to the ova actually work to break down its outer layer.

So this is considered ok to make fun about?
