As a petroleum engineer, I feel somehow slighted.
The only jokes about us are regarding our lawns.
Nah.
Pet E's always have a gas.

Butt, lettuce not grease the skids, lest we end up in the gutter.
We all have enough scents to nose one should never piss off a PetE.
OK - here's one for you (I work with Petroleum Engineers)
What's the difference between an engineer and an accountant?
The accountant knows he's not an engineer.
During the last oil patch downturn an out of work PetE with an MS was submitting applications everywhere. Finally, he gets an interview at a Burger King. The manager is impressed with the guys enthusiasm and intuitive grasp of the fry oil reservoir and he also has a mean burger flip. Eventually though, the manager declines to hire him. As he's leaving, he asks why he didn't get a position and the manager responds... "Well, all of my Petroleum Engineers have PhDs"...
