Mine was 1077 for a while. (The price of a cheese pizza and a large soda at Panucci's Pizza!)

Mine was 1123, the beginning of the Fibonacci Sequence. Obviously it was an easy guess though so it had to be changed.

Ohmygod I just forgot my pin number while thinking of these new possibilities. Chit. Hopefully I'll remember it when I have to get gas later.

me and 3 friends all have the same pin number
1337
yah, i know…lame when compared to the other stuff on the list

I'm amazed how many friends have told me that their PIN spells a nasty word. If I ever get their card, I won't have to try too many before I find it.

Mine was 4067, the PLU for zucchini. I don't like zucchini, and it's one of the few produce codes I have memorized from when I worked at Kroger.

1729, the smallest taxicab number (number expressible as the sum of two cubes in two different ways)
1^3 + 12^3
10^3+ 9^3

The next Munchausen number after 3,435 is 438,579,088.

This is all fun, but when will you actually be able to tell anyone this..

4 8 15 16 23 42 108?

Kinda makes me want to change my pin…

3435 is my new favorite number. Suck it other number I am not naming!
