Sheldon Cooper's 73 Hoodie

Sheldon Cooper's 73 Hoodie Now you can sport the 73 T-Shirt (Now in a hoodie!) that Sheldon wears because after all 73 is the best number. Why you may ask, well... 73 is the twenty-first prime number. Its mirror, 37, is the twelfth and its mirror, 21, is the product of multiplying (hang on to your hats) 7 and 3.... In binary, 73 is a palindrome: 1-0-0-1-0-0-1, which backwards is 1-0-0-1-0-0-1."  Now you know why 73 is the best number. Professionally screen printed on a super soft 50% cotton, 50% polyester Gildan Hoodie. Need to see our Size Chart? All our Hoodies are printed in the good ol' USA.
