A polar bear walks into a bar.
Bartender: "what can I get for you?"
Polar bear: "I'll have a gin and ................(insert long pause) tonic"
Bartender: "what's with the big pause?"
Polar bear (holding up his paws): "oh, I don't know, my dad had them too"
Knock-knock... who's there?
Interrupting cow... interrupting cow (MOOO) who?
