Scared Number

Listen up, buttercup! The joke plays on the fact that "7 8 9" sounds like "7 ate 9." Then it throws in a dark twist by saying 10 is scared because it's between 9 and 11, referencing the 9/11 terrorist attacks on the Twin Towers. The joke uses dark humor by combining a children's rhyme with a real-life tragedy. You probably trip on flat surfaces.
