The pun to end all puns.

I was recently reacquainted with the best pun I’d ever read, perhaps even the best pun on the Internet ever. Here’s the setup, a posting to AskReddit:

I’m 85% certain that there is an adult actress in my philosophy class.

Probably Lexi Belle, but I don’t know. Any suggestions on how I can know for sure? It would be too hard (and unethical) to take a picture and put it up here… and going up to her and saying, “Don’t I know you from somewhere?” would probably be a bad idea.

To which someone proposed:

Ask Lexi Belle if she has any interest in philosophy. If she says yes, then ask her which philosophers she likes. Once you get her answer, strike up a conversation with the girl in your class about these very philosophers. This will get you laid.

And then our hero, dart22, replied with the epic pun:

Isn’t this putting Descartes before the whores?

Please enjoy.
