There's a great joke about a pig calling an industrial supply company to order a whole bunch of sealed spherical bearings. After the pig is placed on hold, he waits patiently for a few minutes, humming along to the music. But then, the pig gets spooked and drops his cell phone in the watering trough and the call is terminated. 

That's all of the joke we can remember, but you'll have to trust us - it was funny.
