Since we are engineers AND we're from Akron, we're probably all used to being the brunt of an occasional joke, right?
But isn't it healthy to laugh at yourself (or others) every once in a while?
With that in mind, here is a selection of various engineering related jokes:

What is "pi"?

Mathematician: Pi is the number expressing the relationship between the circumference of a circle and its diameter.

Physicist: Pi is 3.1415927 plus or minus 0.000000005.

Engineer: Pi is about 3.

The Job Interview

A mathematician, an engineer, and a physicist are being interviewed for a job. In each case, the interview goes along famously until the last question is asked: "How much is one plus one?" Each of them suspects a trap, and is hesitant to answer.

The mathematician thinks for a moment, and says "I'm not sure, but I think it converges". The physicist says "I'm not sure, but I think it's on the order of one". The engineer gets up, closes the door to the office, and says "How much do you want it to be?"

Chocolate Chip Cookie Recipe
Why engineers don't write cook books................
Ingredients:

1.) 532.35 cm3 gluten
2.) 4.9 cm3 NaHCO3
3.) 4.9 cm3 refined halite
4.) 236.6 cm3 partially hydrogenated tallow triglyceride
5.) 177.45 cm3 crystalline C12H22O11
6.) 177.45 cm3 unrefined C12H22O11
7.) 4.9 cm3 methyl ether of protocatechuic aldehyde
8.) Two calcium carbonate-encapsulated avian albumen-coated protein
9.) 473.2 cm3 theobroma cacao
10.) 236.6 cm3 de-encapsulated legume meats (sieve size #10)

Directions:
• To a 2-L jacketed round reactor vessel (reactor #1) with an overall heat transfer coefficient of about 100 Btu/F-ft2-hr, add ingredients one, two and three with constant agitation.

• In a second 2-L reactor vessel with a radial flow impeller operating at 100 rpm, add ingredients four, five, six, and seven until the mixture is homogenous.

• To reactor #2, add ingredient eight, followed by three equal volumes of the homogenous mixture in reactor #1. Additionally, add ingredient nine and ten slowly, with constant agitation. Care must be taken at this point in the reaction to control any temperature rise that may be the result of an exothermic reaction.

• Using a screw extrude attached to a #4 nodulizer, place the mixture piece-meal on a 316SS sheet (300 x 600 mm). Heat in a 460K oven for a period of time that is in agreement with Frank & Johnston's first order rate expression (see JACOS, 21, 55), or until golden brown.

• Once the reaction is complete, place the sheet on a 25C heat-transfer table, allowing the product to come to equilibrium.
