My kids watch this show. This appears to be one of the only interesting comments to come from it:
"The best number is 73. Why? 73 is the 21st prime number. Its mirror (37) is the 12th and its mirror (21) is the product of multiplying, 7 and 3. ... In binary, 73 is a palindrome, 1001001 which backwards is 1001001."
-Dr. Sheldon Cooper, (Jim Parsons), "Big Bang Theory"
"Just to invite your attention to "73" in Morse code--also a palindrome."
