Joke

Three men met at a party, and it wasn't long until the conversation got around to their line of work and what kind of cars they drove.

"I'm a veterinarian", said the first fellow. "So, naturally, I drive a white 'Vet".

As they smiled and nodded, the second man said, "I own a sign company, so I drive a purple Neon". Now the third guy was suddenly quiet until he was egged on by the other two.

"Well", he finally said, "I'm a proctologist... and I have a brown Probe."
