Two mute guys wanted to have some fun on a weekend but they agreed they must go to the gas station and buy some condoms. One guy asked the other using sign language:

I can’t talk, how can I make the clerk understand that I want condoms?

The other responded: just open your zipper, show your thing to that guy and put a five dollar bill on the table, he will understand.

So the first guy went and did what his partner told him to do. However he came back without any condoms in his hands.

His partner asked him what happened.. he went: well I did exactly what you said, when the clerk saw my dick and the five dollar bill, he unzipped his pants and showed his dick. His was bigger than mine so he took my five dollar.
