Bypasing a common firewall

[dburner]

Hello, I need a little bit of help

I made a little script to make some pranks on my friends. Its a simple TCP client and server. I use them to send strings then on my friend's computer appear message boxes with the title and text that I want. I send them texts like "System error, your computer is too unstable and it will blow up in 10 seconds".

The problem is some of them have firewalls. Can someone please help me to bypass their firewalls.
