.06. [VOICE] a joke about john marston & robert capa
A cowboy and a physicist walk into a bar. (I don't know why, they just do.) The cowboy walks over to the physicist and is complaining about how his horse can't run as many hours as it used to be able to. The physicist listens to him, asks a few questions, and then says he'll think about it, right?

The cowboy, excited to know how to fix his horse, asks how. The physicist says, "First, we assume a spherical horse in a vacuum.."
