A five-year-old and a four-year-old decide to start swearing...

A five-year-old and a four-year-old are upstairs in their bedroom.

"You know what?" says the five-year-old, "I think it's about time we start swearing." The four-year-old nods his head in approval. The 5-year-old continues, "When we go downstairs for breakfast I'm gonna say "hell", and you say "ass", okay?" The four-year-old agrees with great enthusiasm!

The mother walks into the kitchen and asks the five-year-old what he wants for breakfast, "Aw hell Mom, I guess I'll have some Cheerios."

.....WHACK!

He flies out of his chair, tumbles across the kitchen floor, gets up, and runs upstairs bawling.

The mom looks at the four-year-old and asks with a stern voice, "And what do YOU want for breakfast, young man?" "I'm not sure," he says, "but you can bet your ass it won't be Cheerios."
