mIRC script

Hey, I have never used mircscripts.
I like the way you can put little comment like this one "S slaps d around a bit with a large trout". etc.
Can someone tell me what script is that?

i have used from some time NoName Script and it was really good,then i got bored with him and now i dont use any atm,but will see some of the scripts that have been said here

and i have to say extreme script is great as well !
