A 5 year-old and a 4 year-old were upstairs in their bedroom.
"You know what?" said the 5 year-old, "I think its about time we start swearing."
The 4 year-old nodded his head in aproval. "When we go downstairs for breakfast I'm gunna say 'hell' and you say 'ass', OK?"
"OK." The 5 year-old said with enthusiasm.
The mother walks into the kitchen and asked the 5 year-old what he wanted for breakfast. "Awe, hell mom, I guess I'll have Cheerios."
Whack!! He flies out of his chair, tumbles across the kitchen floor, gets up, and runs out of the room sobbing.
The mom looks at the 4 year-old and asked in a stern voice, "And what do YOU want for breakfast, young man?"
"I don't know," he blubbers, "but you can bet your ass it won't be Cherrios!"
