Thanks masterzora. This one isn't dirty, but I think it is a pretty good joke about how when approaching a problem mathematicians usually try to simplify the situation as much as possible.
How a mathematician would model milk production:
"Assume a spherical cow of radius R, uniformly filled with milk"
Okay, so there's a physicist and a mathematician in a room. Suddenly and inexplicably a fire starts. The physicist immediately grabs a bucket, fills it with water, and puts out the fire. The next day the same two people are in the same room adn suddenly and inexplicably another fire starts. The mathematician immediately grabs the bucket and hands it to the physicist, thereby reducing it to a previously solved problem.
