Request - Sound

I was wondering if anyone could somehow make it to where where when i kill someone, or a match is starting if you could make it say " Leeerrrrooooyyyy Jeeeennnnkkkiiinnnsss!!!!" <-- If you don't know what it is...Youtube will help you find the answer. It would really be appreciated if you could do this

-Peace (and btw how do i setup custom kill badges that i download?Sorry if I sound like a noob. )

I use one it was kill sounds of DOTA-its a game with sick fking sound.
just search it SUPS CF SOUND PACK or something like that.
