Have you ever made a prank phone call and got someone really mad? Talk about it here

I remember when I was about 16 me and my friend made a prank phone call to a random person over the phone. My friend told me to ask the guy in Beavises voice from Beavis and Butthead "Are you butt naked?" After I done that I quickly hung up. The guy called back with *69 and told my friend if he ever does that again he would blow the house up (Scary).
