Swearing

A seven-year-old boy and his four-year-old brother were upstairs in their bedroom. "You know what?" said the seven year old. "I think it's about time we start swearing."

The four year old nodded his head in approval.

"When we go downstairs for breakfast, I'm gonna say hell, and you say ass¹, okay?" The four year old agreed with enthusiasm.

The mother walked into the kitchen and asked the seven year old what he wanted for breakfast. "Aw hell, Mom, I guess I'll have some Cheerios."

WHACK²! He flew out of his chair, tumbled across the floor, got up and ran upstairs crying his eyes out. The mother looked at the four year old and asked with a stern voice, "And what do you want for breakfast, young man?"

"I don't know," he blubbered, "but you can bet your ass it won't be Cheerios."
