Playground jokes

from my 7 y/o: Why did the chicken cross the playground?

To get to the other slide

A prisoner has been digging up a tunnel under his cell for years

One day he while he was digging he saw the light, he reached the end of tunnel and ended up in a kindergarten playground

"I'm free, I'm free!" shouted the escaped prisoner

"so what? I'm four" said one of the toddlers
