<human>: Condense the text into a few key points

I posted the following creepiness in a thread about an hour ago. It made me wonder about other folks.

Basically, a friend of mine was sleeping over and we were painting our nails. I turned off all the lights but turned on this revolving disco ball light I had. I turned on the radio and [Buggles - Video Killed The Radio Star] was playing.

I turned it up and I started to cackle like a maniac and jump on my bed, knocking things over on my dressing table. Then I grabbed one of my sharp cuticle pushers, sat on her stomach, grabbed her arm, and cut it. She started crying and I freaked the fuck out and realized what I had just done. I quickly put on my normal face and said I was joking. She relaxed and I got her some ice cream and joke books. 

Anyway, pretty sure she forgot about it now. I don't know. She moved to Ireland shortly after.
