73 

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"

Rule 73 

If something naughty or unacceptable is said on a "safe" website and nobody understands it, you do NOT explain it.

Harry: "I know what Rule 34 is, and I don't think you should be mentioning it here."

Jinzo: "Rule 73. I think you just got me banned. Thanks for that."

73 some 

The ultimate goal of a militant Islamic. It stems from the belief that they will be rewarded with 72 virgins in heaven if they die for Allah.

Bill: Dude I just had a 3 some with those wicked hot cheerleaders!
Achmed: I can beat that.
Bill: Oh yeah? Go ahead and try.
Achmed: I'll pull a 73 some right now. ALLAH-LAH-LAH-LAH-LAH-LAH!!!! *BOOM*
