Maybe I just have a dirty mind.
// Disclaimer: Without this disclaimer, someone will take me seriously and try to explain this to me. *sigh*
Computer Engineers sometimes do it on the bus.
Pediatrists do it one foot at a time.
Medical Biophysists do it with doctors AND physists at the same time. (for akhan246)
I have to completely agree especially with
"Astronomers Do It With White Dwarfs and Red Giants"
"Biologists Evolved To Do It Better"
"Chemists Do It In An Excited State"
"Circuit Designers Have A Very Low Rise Time"
"Economists Do It With Models"
"Spectroscopists Do It Until It Hertz"
The Molecular Biologist one is pretty lame as well. Those are the two I really wanted besides the statistics one.
