#1. [Heard in organic chem lab at the College of Charleston]: New student: I think I'll need some concentrated acetone to get out all the water in the beaker. Lab TA: Yeah, and when you find that, see you if you can find the bottle of dilute water. #2. [Also heard in chem lab]: Student A: Knock knock. Student B: Who's there? Student A: Aldehyde. Student B: Aldehyde who? (Few moments of silence.....) Student C: Hmmn, he's gone. Must have been a leaving group. #3. [On my first day at the Department of Immunology, at the Medical University of South Carolina] Co-worker: Never mess around with people in the lab. 'Cause the next time you turn around, someone might take a leak in your cultures.
