Quote from Rose in The Housekeeper
Blanche: I wonder what this is. Rose: I'll bet it's a love potion. Dorothy: Ah, Rose, come on, honey. There's no such thing as a love potion. Rose: Sure there is, Dorothy. My grandparents got together because of a love potion. Well, actually it was a foot salve Gramps accidentally swallowed. You see, Grandma was the nurse who pumped his stomach, but she was new and she attached the nozzle to the wrong place. Next thing you know, they were engaged.
