Feel free to browse the collection of tall tales, yarns and downright lies. They are all family safe - the test I apply is "would I tell this to someone's grandmother?" If no, I don't use it. (That doesn't mean i don't appreciate a dirty joke, but I don't think they're appropriate for broadcast on the radio - you never know who is listening or how old they are or what their attitudes to dirty jokes amounts to. )
A second grader came home from school and said to her mother, "Mom, guess what? We learned how to make babies today."
The mother, more than a little surprised, tried to keep her cool. "That's interesting," she said "How do you make babies?"
"It's simple," replied the girl. "You just change "y" to "i" and add "es."
(Why wouldn't an English teacher love that one?)
