Rules 29 & 30

Referring to The Rules of the Internet. Possibly the most important rules of them all.

Rule 29 states: In the internet all girls are men and all kids are undercover FBI agents.

Rule 30 states: There are no girls on the internet.

Very useful rules to know while using online chat rooms.

EXAMPLE 1--

normal teenager: r u a girl or guy?
girl(not): im a gurl.. cant u tell? <3
normal teenager: bitch step off i know rules 29 & 30

EXAMPLE 2--

strange man: So you're 7, eh?
little boy(not): yes, why?
strange man: rly? im 8. do you want to meet in real life sometime??
little boy(not): Sir, this is FBI agent Michael Scarn, I hereby place you under arrest. Anything you say can and will be used against you.
strange man: DAMN. I wish I'd remembered rules 29 & 30.
