Timbuktu

In the finals of a national poetry contest, the last two contestants are a Harvard graduate and a redneck. The Harvard graduate steps forward to receive the last subject. The judges tell him 'Timbuktu'. He thinks for a moment and recites his poem:
Across the vast and open sands
March a lonely caravan.
As they march, two by two
Destination Timbuktu
The crowd goes wild as the redneck steps forward. The judges tell him his subject is Timbuktu. He thinks for a while, when a big grin spreads across his face.
A huntin me and my friend Tim went.
We found three whores in a pop-up tent.
Of them were three, and of us were two,
so I bucked one and Tim-buck-two!
