Two travelling salemen needed a place to stay for the night, so they decided to walk up to a farmhouse and ask if there was any room there for them. The farmer replied "Well, yes, as a matter of fact, I do have room for you. There's bunk beds in the corn crib that you're welcome to, the only catch is that one of you will have to sleep with my daughter."
Well, they were dead tired, so they took him up on the offer, but one look at the daughter was enough to almost scare them off. But...they were tired, so they drew straws to see who was unfortunate enough to not sleep alone. The loser climbed up into the top bunk with the daughter, and the winner slept in the bottom bunk.
Well, now...the daughter was a frisky sort and kept pestering the guy. He eventually figured out that the only way he was going to get any sleep was to satisfy her. But, this being the usual "wouldn't touch her with yours" case he was very, very reluctant to, until he had the brilliant idea of reaching over for a corn cob. That worked wonderfully! He went through about a dozen of them before she finally laid back, satisfied.
After a while he was woken up when his partner said from the bottom bunk....
"Hey, butter up anther one... that corn was delicious."
