OMG. I worked for an engineering firm one summer during college, and I had just broken up with my boyfriend of 2 years. Sad, lonely and horny. I was in the drawings department, logging in and reproducing mechanical drawings. The names of all those parts were making me horny every day!
Examples: bushings, hot box, nipples, [censored], ball, nut, screw, stud, coupling, flexible member, gland, mating ring, rigid shaft, stuffing box, suction head, thrust bearing, wet end.

Now, how do people who work in this field ever get anything done? I was daydreaming 8 hrs a day at my desk!!
