What's Under Your Bed

Three jockeys were enjoying a night's drinking. As the evening passed
they became more and more morose.

The first jockey said "My wife's having an affair with an electrician!"
When asked how he knew he explained that he had found a voltmeter under
his bed.

The second jockey also admitted that his wife had a lover, but that he
was a plumber as he'd found a monkey wrench under his bed.

The third jockey was by now looking really depressed and after some
urging admitted that his wife was also having an affair, but that he
knew that she was sleeping with a horse!

Asked how he knew the third jockey replied, "Last night I came home and
found a jockey under my bed!"
