When I was about 17 or 18 one of my good friends, a girl, started acting really weird around me and her parents would too on the phone. Then after about three days of this her father got on the phone and told me he knew it was me calling them and making obscene phone calls. I was like WTF? Dude, have the phone line traced, you'll see it wasn't me. He said they did and it came back to my house!
Double WTF!
Well, it turns out this creepy fucker that was my room mate at the time would sneak into my room and use my phone when I wasn't there. I confronted him about it and after lying for a few hours he gave in and admitted what he did it. I then beat the shit out of him for about 10 mins; broke his nose and his right hand with the phone handle. I got into a little trouble over that... and that's the story of how I joined the military.
