A woman was having an daytime affair while her husband was at work. One rainy day, she was in bed with her boyfriend when, to her horror, she heard her husband's car pull into the driveway.

'Oh my God - Hurry! Grab your clothes and jump out the window. My husband's home early!'

'I can't jump out the window,' the boyfriend replied. 'It's raining out there!'

'If my husband catches us in here, he'll kill us both,' she replied. 'He has a bad temper and he also has a gun!'

So the boyfriend scoots out of bed, grabs his clothes and jumps out the window. As he runs down the street in the puring rain, he quickly discovers that he has run into the middle of the town's annual marathon. So he starts running along beside the other runners, about 300 of them.

Being naked, with his clothes tucked under his arm, he tries to blend in as best he can. After a little while a small group of joggers who have been watching him with some curiosity, jog closer.

'Do you always run naked?' one asks.

'Oh yes. It feels so wonderfully free,! he replies.

Another runner moves along side and asks,  'Do you always carry your clothes under your arm when you run?

'Oh yes,'  the man answered breathlessly. 'That way I can get dressed right at the end of the run, get in my car and go home.'

Then a third runner glances down and asks, 'Do you always wear a condom when you run?'

The man replies, 'Only when it's raining!''
