Funny chat glitch

Its quite simple, and I guess useless in a way but you get attention and people asking you how you do it.

This glitch makes your text go outside of the chat box for everyone. Its not just for you, but everyone will see the text outside of their chat boxes. Problem is so far I've only managed to get it to be question marks. But its funny so I thought I'd share it with my favorite wow site.

All you do is open chat--> hold CTRL + ALT and E. Then spam question marks untill it reaches its limit and enter.
