Cletus was issued a challenge by his lawyer friend, which Bob accepted:

Lawyer: Every time you can't answer a question I ask, you have to pay me $5. But every time I can't answer one of yours, I will pay you $5000!

Cletus: Deal!

Lawyer: How many countries are there in the world?

(Cletus hands over $5)

Cletus: What animal has 3 legs, but has 4 after it climbs up a hill?

(Lawyer looks all over for the answer, but can't find it)

Lawyer: Ok, I give up! (hands over $5000) What's the answer to your question?

(Cletus hands over $5....)
