Two worms

One afternoon, two worms were crawling through the grass. The male worm said to female worm, "How about if you and I go back to your place?"

The female worm said, "Okay." So, the two worms went back to her place and the male worm noticed that the female worm is wearing a wedding ring.

The male worm said, "I'm sorry honey, but I don't do this sort of thing with married worms."

The female worm replied, "Don't worry. My husband is not coming home."

The male worm asked, "How do you know that for sure?"

The female worm answered, " Well, he got up early this morning and went fishing."
