The wife always screws around with the mailman while the husband is working.
One day, when they were still on the bed, they heard the car door closing, so the wife anxiously told the mailman "There's no time! Just take your clothes and jump out the window!"
Coincidentally, he jumped into a group of people who are running marathon, so he had to run along with them while holding his clothes.
One of the runner asked "Do you usually run naked?"
The mailman replied "Yeah, I like the feeling of breeze brushing through my skin"
Another runner asked "Do you usually run while holding your clothes?"
The mailman replied "Yeah, this way I can just put my clothes on after running, and drive straight home"
The runner asked again "Do you usually run with a condom on?"
The mailman replied "Only if it rains"
