7676
This number spells "porn" while texting if you push the buttons enough times (those of you who text, try this and it is true.).

Also, disturbing fact: my school's last four digits are...yup, u guessed it: 7676.
No joke.

Also this is good for online chatting or forum posting while there is a PA (parent alert).
