A man walks into a bar with an owl on his shoulder.

He says to the bartender "I bet you a hundred bucks this owl can talk!"

The bartender accepts and tells the man to prove his claim.

The man turns to the owl and says "Who gives you water and lovely owl food every night?"

The owl answers "H'you!"

The man asks the owl "Who was the President of China from 2003 to 2013?"

The owl responds "Hu!"

The man asks "What's the greatest British rock band of all time?"

The owl promptly answers "Who!"

The bartender has had enough of this nonsense and he throws the man and his owl out of the bar.

As the two of them are sitting in the alleyway, the owl turns to the man and says "Led Zeppelin?"
