Three men were discussing their careers and the vehicles they drove.



Im a veterinarian, said the first fellow. So, naturally, I drive a white Vette.



The men smiled in amusement.



The second man continued, I run a sign company, so I drive a purple Neon.



The men smiled and the first two now looked at the third to hear his answer. However, the third man was unusually quiet. The first two men prodded him to answer since they had each given theirs.



Well, he finally spoke, Im a proctologist and I have a brown Probe.
