Convert AVI To Ringtone?

Hey Forum :D

I browsed through all of the Movies/TV Show Ringtones that CB has to offer, but I didn't see any for this TV Show..

I'm looking for some funny Quotes from the TV Show "Blue Mountain State" to set as my ringtone

Its not the most popular TV show around, but it is very funny :cool:

Oh, and also Trailer Park Boys!

If someone could tell me how to convert an AVI file to a Ringtone that would be awesome!
(Looking for a program that is simple to use, even if it just converts the full AVI file to MP3, and then let me clip it like "makeownringtone")

and hey, if you have some BMS or TPB Ringtones you think I would like, post it up! :D

Thanks!
