For a while I gathered up as many math jokes as I could find online. I cleaned them up and formatted them, and stuck them all in a database. Now they're here, if you log in you can rate them, and keep a collection of your favorites.
Mostly so I could see about playing around with things, there's another way to access an individual joke. If you send 'Accept: text/plain' in your HTTP header to a '/jokeN' page (for example, an address you get redirected to by clicking on 'Random'), a plain text file with the joke will be returned. The first line will be the title. If there is a reference, it will be on the second line, with '--- ' before it. The remaining lines will consist of the joke text.
If you notice that a joke displays poorly, has formatting issues, or if you feel you (or your website) was not properly referenced for a joke, please contact me.
