Dr. Knucklehead's Knock-knocks

<p>Dr. Knucklehead is knock-knocking at the door and children will happily answer, because they love knock-knocks - and these are the very best. Try this: <i>Knock Knock</i>. Who's there? <i>Daisies</i>. Daisies who? <i>Days he's a man, but by night, he's a werewolf!</i> Or laugh a lot at this: <i>Knock Knock</i>. Who's there? <i>Billows</i>. Billows who? <i>Bill owes me ten bucks and he said you'd give it to me</i>. Every one is riotously funny.</p>
