Hmm, the SOS could be useful for this situation (and trust me it happsn often):
Me = Anyone seen the remote?
Party B = Nope
Me = Are you sure?
B = Yep.
So I spend half an hour tearing the house apart (just so I dont have to get up and change the channel manually), I literally tear the room apart and eventually find the remote... under the arse of party B.
So if the SOS was sent when the tv is first turned on they might get here in time to stop me from beating someone to death with the remote control.
