A crude but funny moment at the livestock auction

We are at the Lazy H livestock auction and I just witnessed southernality at its finest.
One of the workers was tagging goats in the back while I was looking some over. His about seven year old son was helping write the tag numbers and open the gate. As his dad grabbed a very rambunctious small goat he yelled for his son to hurry over and tell him if the goat was a nanny (girl) or a billy (boy). The boy looked between its legs but was having trouble identifying this squiggling goat. In frustration as the dad continued to wrestle the mad goat he yelled in a deep cornbread fed Southern accent to his son " Balls or nipples, boy?! Balls or nipples?!"
I don't know why this was so funny to me. It may be one of those things you would have to be there for but I thought I'd share. ;-)
