A seven-year-old tells his four-year-old brother that they should start swearing. "When we go downstairs for breakfast, I'll say 'hell' and you say 'ass.'" The four-year-old happily agrees.
At breakfast, the seven-year-old says, "Aw hell, Mom, I'll just have some toast."
The surprised mother quickly smacks him. The boy runs upstairs crying. The mother turns to the younger boy, "And what would YOU like for breakfast?"
"I don't know," the four-year-old blubbers, "but you can bet your ass it's not gonna be toast!"
