When someone tells the same joke over and over, apparently in the belief that, although it was completely lame the first 50 times, at some point between the 51st and 2057th times, it will magically become funny.
Monday
Dan: You love the penis so much.
Tuesday
Dan: Why do you love the penis so much?
Wednesday
Dan: I'd like you better if you didn't love the penis so much!
Thursday
Dan: You still love the penis way too much.
Joe: Quit with the goddamn Dan Jokes already!
Dan: Ok, I'll quit... just as soon as you stop loving the penis so much!
Joe: I hate you.
Dan: You love the penis so much.

After a joke has run its course, a certain person continues to tell jokes similar or realting to the already not funny joke, thus pissing everyone else off.
