Letting Down jokes

What is the difference between 9/11 and rickrolling?

The Twin Towers gave up and let down.

Your mom is just like Rapunzel, but instead of letting down her hair, she lets everyone down! OHHHHH!

There was a man in a tower, and the other man thought it was a girl, so he said, "Let down your long hair." He said, "OK, I will let my big, super long, hairy penis down for you to climb and suck." Then the other man said, "If you have such a long dick, suck it yourself. See ya, b*tch."

Roses are red, chocolate is brown,

I expect nothing and still get let down!
