You all know little Johnny. Sometimes he sneaks on his dad's computer and looks at the humour forum. One day he could not resist and typed in a joke which was very popular with his 11 year old mates. It got promptly moderated for at least 4 different reasons. Johnny was very upset about it, so he posted a message to the moderator asking;
"Why is that so?"
And the moderator, being a wise old person and knowing Johnny's exploits, answered as follows:
Johnny, son, the Whale is the biggest animal on earth but has the smallest throat of all. However, it feeds on the smallest creature in the sea, the plankton.
