Two scouts walk onstage. One brags about how big his muscles are as he flexes his arms. The second scout wants to know what he has to do to build up his muscles.
"What do I need to do to be big a strong like you?"
The first scout tells him the secret:
"Every night, before I go to bed, I go to the kitchen and put oil on my arms. Give it a try tonight and let me know how it works."
Both exit the stage...
Later, both enter, but the second is crawling on his knees.
"My Arms Shrank!! I thought you said it would work!!"
"Well, what did you use?" asks the first.
"Crisco," answers the second scout.
"What!! That's shortening!" replies the first scout.
