National Knock Knock Joke Day is celebrated every October 31^st – and often outdone by the more popular Halloween holiday. Today, Big Dot has decided to honor both, giving true knock knock joke aficionados their time in the spotlight.

To celebrate two favorite party themes, the Big Dotters have chosen a favorite knock knock joke to get the day started off right:

Knock-knock.
Who’s there?
Moo.
Moo, who?
Well, make up your mind, are you a cow or an owl?

What’s your favorite knock knock joke?
