A mathematician, a physicist, and an engineer are all given identical rubber balls and told to find the volume. They are given anything they want to measure it, and have all the time they need. The mathematician pulls out a measuring tape and records the circumference. He then divides by two times pi to get the radius, cubes that, multiplies by pi again, and then multiplies by four-thirds and thereby calculates the volume. The physicist gets a bucket of water, places 1.00000 gallons of water in the bucket, drops in the ball, and measures the displacement to six significant figures. And the engineer? He writes down the serial number of the ball, and looks it up.

This reminds me of another one...
The physicist suggests using rocks and some large sticks. Applying leverage at the correct point, the can should be penetrated.
The chemist suggest heating the can till internal pressures force it open.
The economist when asked says the following:
"Assume a can opener...."
