Turk: Sir, I am so sorry. Mrs. Kaye told me about picking up her grandkids, and she said she was feeling fine, and I believed her.
Dr. Kelso: Doctor, follow me. Son, have you used drugs in the last 48 hours?
Young Man: Oh, no, sir. Never use drugs.
Dr. Kelso: Because this shot you're about to get could kill you if it's mixed with narcotics.
Young Man: Oh, drugs. Yes, sir, all the time.
Dr. Kelso: See? Waiting for the tox screen, six hours. Frightening the bejeebies out of the riffraff, ten seconds. Everybody lies, Dr. Turk, whether it's that doobie brother in there, or, say, me when I tell my son he can still live at the house after he graduates from art school. And by the way, sport, Mrs. Kaye doesn't have any grandchildren.
