One day, Jimmy is walking home from school. When he gets home, he finds his grandpa sitting on the Porch without any pants on!

So he goes up to his grandpa and says Grandpa, do you realize that youre not wearing any pants? His grandpa replies Yes Jimmy, I do.

Jimmy then says Well, why are you outside without any pants on Grandpa?

His grandpa looks at Jimmy and responds Well Jimmy, yesterday I sat outside without a shirt to long, and I got a stiff neck. This was your grandmas idea.
