A nipple.


An army camp stationed in the desert had just received a new commander. During the commanders first inspection everything checked out except one thing. There was a camel tied to a tree at the edge of the camp. Having asked what it was for, one of the soldiers started to explain to him that the men sometimes get lonely since there were no women there. The commander stops him short, not wanting to hear anymore, and they go along their way.

A few weeks pass, and he too starts to miss his wife, so he orders the men to bring the camel into his tent. After about an hour the commander comes out, zips up his pants and says, "So is that how the other men do it?" The soldier responds, "Nah, we usually just ride the camel into town."
