My wife's maid-of-honor had no idea what GHB (date rape drug). Once while at a party, my brother-in-law added sum rum to her soda bottle, put the cap back on, and handed it to her. She asked what it was and he told her "It's your soda, but I put GHB in it." She thought it was some type of alcohol and professed at her difficulty opening the cap:
"I can't open my GHB with my nails on!"
