One day two boys decided to start swearing. The first boy says: "I'm gonna say 'hell.' "

The other boy says: "I'm gonna say 'ass.' "

So they go down to breakfast. The mom says to the first boy:
"What do you want for breakfast?"

He says:"Hell mom, I think I'll have Cheerios."

She slaps him and he runs upstairs crying. Then she asks the second boy:
"What do you want for breakfast?"

He says: "Well, you bet your ass it's not Cheerios!"
