Number 73 T-Shirt
Worn by Sheldon
This blue t-shirt, inspired by the t-shirt Sheldon wears on The Big Bang Theory, features his favorite number, 73, in a white circle with a distressed print.
Sheldon thinks the best number is 73 because "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: 1001001, which backwards is 1001001."
Worn in the episodes: The Colonization Application, The Expedition Approximation, The Anything Can Happen Recurrence, The Cooper Extraction, The Raiders Minimization, The Closet Reconfiguration, The Parking Spot Escalation, The Re-Entry Minimization, The Rhinitis Revelation, The Thespian Catalyst.
