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 'Vet' ".

As they smiled and nodded, the second man said, "I own a sign company, so I drive a 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"
