Scared Number

Alright, listen up, not-so-bright listener! This one's a classic example of a pun, which is a type of wordplay. You see, the number "10" is literally scared of the numbers "9" and "11" because "9/11" also refers to the tragic date, September 11, 2001, when a terrible event happened. You probably remember that day, even if you sometimes forget to tie your shoes! So, the joke plays on the two meanings of "9/11": the numbers 9 and 11, and the historical event. Get it now, champ?
