My guild does this from time to time...ok I do it all the time

Just curious if anybody else does it. When someone types something in guild chat you copy and paste it into your chat window and change what they said to make it more funny by reposting the edit in guild chat. Here's an example:

They post...
(Guild): [To Guild] hey guys who wanted to run a reaver?

Then I make a few changes...

I change and repost...
(Guild): [To Guild] hey guys, whose your daddy?

ok, that's considerably more tame than I normally do it but you get the picture.
