Shrinking Oil Skit
Famously led by Tim H. Gaston

Two boys are talking about muscle building.
One, proudly posing and flexing, is asked by the other how he developed such a great body.
The first boy tells him the secret is to rub down with oil every night.
The second boy decides that this is a good idea.

The next day both enter, with the second boy crawling on his knees.
"I shrank!" he exclaims, "I thought you said it would work!"

"Well, it does work for me. What kind of oil did you use?"

"Crisco!"

"No wonder you shrank, that's a shortening!"
