Grandma and Grandpa were sitting on their rocking chairs one lazy afternoon, Grandpa started feeling spry and reached over and gave Grandma's breast a squeeze and said "You know Ma, if this would give milk we could get rid of the cow."
To that Grandma said, "Yep we sure could."
After a while Grandpa reach over to Grandma's crotch and gave it a pat and said, "You know Ma, if this could give eggs we could get rid of the chickens."
Grandma said, "Yep we sure could."
After a short while Grandma reached over to Grandpa and started stroking his Jewels and said, "You know Pa, if this could get hard we could get rid of your brother.
