A woman was sure that her husband was cheating on her, and having an affair with the Maid. So she laid down a trap. 
One evening she suddenly sent the maid home for the weekend & didn't tell the husband. 
That night when they went to bed, the husband gave the old story: "Excuse me my dear, my stomach aches", and went to the bathroom. 
The wife promptly went into the Maid's bed. She switched the lights off. 
When he came in silently, he wasted no time or words but had his way with her.... 
When he finished and was still panting, the wife said: "You didn't expect to find me in this bed, did you?" 
And then she switched on the light...
"No madam", said the Gardener.!!!!
