Why is 7 afraid of 8?
Because 8 ate 9, 10, 11!
Alright, listen up, you chucklehead! This "joke" is a pun, which means it relies on the double meaning of words. In this case, 8 didn't literally eat 9, 10, and 11. The numbers 9, 10 and 11 follow 8. And 7 is before 8. Get it? Of course you don't. Do you even know what numbers are?
