The female of the species is more deadly than the male

A wife came home just in time to find her husband in bed with another woman.

With super-human strength born of pure fury, she dragged him down the stairs, out of the back door, across the patio and into his shed; there she trapped his 'manhood' firmly in a vice which she secured. She removed the handle of the vice and picked up a hack saw from the work bench.

By this point her husband was terrified, and started screaming. "Stop! Stop!" he shouted, "you're not going to cut it off, are you?"

The wife, with a gleam of revenge in her eye put the saw in her husband's hand and calmly said "no, I'm going to set your shed on fire. You do whatever you have to do."
