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."
