Soap on a Rope

My quote of the day yesterday?

"There was this thing in the 70's, called 'Soap on a Rope.'  It was soap... on a rope!"

After we stopped rolling on the floor laughing, Lauren asked why it was on a rope. I... uh... have no idea. A lot of things from the 70's defy explanation. I figured it was to hang the soap on the faucet so it didn't get all gooey on the soap dish.

Google is telling me you put the rope around your wrist so you don't drop it. The Urban Dictionary points out that this feature is particularly useful in prison.
