One that I saw on reddit (CW: Hitler, suicide):
* The only good thing Hitler did was to kill Hitler.
* But he killed the person who killed Hitler; that's not so good.

An Medical Doctor and a Ph.D. in Psychology walk into a bar.

The bouncer inquires, "Is this a paradox?"

Some remarks a Latin teacher of mine made:

"Women eyes must be like men's feet: big, black and wet!"

"All girls are pretty. Where are the ugly women coming from?"

I would never be so disrespectful towards the fair sex. :->
