What is the easiest way to do this!!?? This is driving me crazy! I have watched this video to many times the last couple days and still can't get it! I don't have a problem putting the call in like he shows I just can't get it to come out right. Is he saying tooka tooka tooka.....fast or what? It's not a call I would use a lot, I just wanna figure it out.
