While they were playing in their fort one of the boys accidentally stepped in the redneck cousin's finger. The redneck cousin said OW MOTHERFUCKER GET OFF MY FINGER!
The two boys had never heard that word before and asked about it. Redneck cousin explained that was the cool adult word that everyone was using. Delighted with their new word they merrily played through the night and went to bed late.
The next morning Dad is making breakfast and the first little boy drifts into the kitchen.
"What do you want for breakfast?" Dad asked.
"I want some motherfucking pancakes!", The first boy exclaimed. Dad smacks the little boy and admonishes him for swearing and sends him back into his room.
The second boy goes into the kitchen and Dad again asks what is wanted for breakfast. "I want some motherfucking pancakes!", the second boy said. He also gets whacked and sent back to his room, crying.
Redneck Cousin comes into the kitchen and Dad once again asks what is desired for breakfast.
Redneck Cousin says "I don't know, but I sure as HELL don't want any motherfucking pancakes!"
