Sheldon Coopers favourite number
He likes it because 73 is the 21st prime number with it's mirror 37, which is the 12th and it's mirror which is 21 and is the answer to 7x3.
He likes it most because 73 is a palindrome (1001001).
73 fans: "I think 73 is the best because I'm a nerd"

Leonard: "73 is the Chuck Norris of numbers"
Sheldon: "No it's not, all you get from Chuck Norris backwards is Sirron Kcuhc"
