in the 80's, I used to go to a bar that served a shot called a Test Tube Baby, it was whiskey, Bailey's and Grenadine. The Bailey's was put in with a straw at the bottom to keep it from mixing together too much and a drop or two of Grenadine which trailed a red (blood) down to the Bailey's. It was served in a real test tube in a rack like you used to see in science class. Looked gross as hell, the name helped.... lol
They served a million of them.....
