Why is 6 afraid of 7?
Because 7 is more than 6. If 7 wanted, all he'd have to do is subtract 6 from both of them, and suddenly 6 would be nothing, and everyone in numberland would make fun of 6, and 6 would become depressed and get fat after eating a pint of ice cream straight from the tub every day, and eventually become a homeless meth addict. All because 7 wanted to be a jerk one day.
