A woman was having a daytime affair while hubby was at work, however one rainy day, in bed with her boyfriend, she heard her husband's car come into the driveway.
"Hurry! Grab your clothes and jump out the window. My husband is home early!"
"I can't jump out the window. It's raining out there."
"If my husband catches us , he'll kill us both. He has a bad temper and a gun, so the rain is the least of your problems."
The boyfriend grabs his clothes and jumps out the window. As he ran down the street in the pouring rain, he quickly discovered he had run right into the middle of the town's annual marathon, so he started running beside others. Among the the 300 or so runners, being naked with his clothes under his arm, he tried to blend in a group of runners near him who had been watching with curiosity.
One asked, "Do you always run in the nude?"
"Oh, yes. It feels so free."
Another said, "Do you always run carrying your clothes under your arm?"
"Yes. That way I can get dressed at the end of the run and drive home."
A third runner, looking lower, asked, "Do you always wear a condom when you run?"
"No, only when it's raining."
