Used this one in a speech to illustrate how slang words can cause confusion--

There was a penguin called Pubert driving around Arizona. His car started to make a strange sound, so he brought it to the first mechanic he ran across.....Fred. Fred told Pubert to come back in an hour and he would know what was wrong. Being as it was hot, and penguins don't like the heat, Pubert went to an ice cream shop and ate a great deal of vanilla ice cream. With his little flippers, he splashed ice cream everywhere. When the hour was up, he went back to the mechanics. Fred met him outside and said, "Well, it looks like you blew a seal." Pubert, embarrassed replied, "Oh, no, it's just vanilla ice cream, I swear!"
