"An Actual Internet Conversation" joke

This is an actual chatroom conversation from a "local Chatroom"
Joe: I wonder what would happen if you had a sleep number bed, and set it to 69?
Christy:? huh?
Mike: I dont know, but it sure sounds tasty!
Joe: You probably wouldn't understand Christy, you're too pure and innocent.
Christy: Maybe... sounds more like a police code or something
Mike: lol, ya, that's it. "This is the dispatcher, what is your status"
Joe: lol "We have a 69 in progress at the overpass, Officer needs assistance"
Mike: "Move in! Move in! Officer has gone down, repeat, Officer has gone down!
Joe: "Someone better call the fire department, looks like we'll need the Jaws of Life for this one!"
Christy: um.. why do i get the feeling i've started something horrible? o.O
