Honestly, the number 69 jokes just make me want to hurl. It's ... just a number. All sexual connatations it has make me, quite frankly, laugh at the sheer stupidity of it.
If you want to see an uber-leet number, though, check this one out:
7,5317
If anyone can figure out why, you get a cookie.
Good, I don't like little boys.
Haha!
