I used to do this while botting MUDs. Immortals (administrators) would check up on you occasionally, so first my script would send a "mis-channel" communication to make it look like I was actively talking to someone else, then a quick "Ack, sorry" followed by a pause and a "one second". All while simultaneously sending me an SMS so I can take over the communication stream in person.
