Alabama grease gun race 

At the end of Alabama family reunion, all the males form a circle jerk and ejaculate into a single cup. The cup is then emptied into a grease gun, and the youngest male is then to artificially inseminate the oldest female, therefore initiating him into the family tradition.

The winner of the race is the male who's sperm impregnated the female, therefore concluding the Alabama grease gun race.

"Congratulations cletus on winning the Alabama grease gun race."
