Using an LCA110 and a LM555 I connected an RF Parking lot RC to a phone line. Whenever the phone rings a ~1sec 12V pulse is sent to the RC and triggers it.

The video was taken with my N95, sorry for the poor quality :)

You could take the receiver out of the RC and hook it to a TV Remote and hide it in the living room, and change the TV on your folks with a phone call.. haha...
