How to tell a joke...

Kyler has developed a unique style for telling a joke. First of all you start all jokes off with "Knock knock...". Then just before the punch line of a Knock, Knock joke, he starts a new joke. It goes something like this (actual joke to follow):

Kyler: Knock, knock
Dad: Who's there?
Kyler: Soap
Dad: Soap who?
Kyler: Why is a banana yellow?
Dad: Why?
Kyler: Because a banana has arms, hands, legs, feet, eyes, ears. Isn't that funny, Dad. Ha ha ha ha ha....

He says that because there is a Yogurt container that has a banana on it with arms, legs, etc...
