Smart Teen

[retired]

A proud and confident genius makes a bet with a teen.
The genius says, "Hey kid, every question I ask you that you don't know the answer, you have to give me $5.
And if you ask me a question and I can't answer yours I will give you $5,000."
The teen says, "Okay."
The genius then asks, "How many continents are there in the world?" The teen doesn't know and hands over the $5.
The teen says, "Now my turn: what animal stands with two legs but sleeps with three?"
The genius tries and searches very hard for the answer but gives up and hands over the $5,000.
The genius says, "Dang it, I lost. By the way, what was the answer to your question?"
The teen hands over $5.
