Further adventures in commercial radio

The radio station that my colleague has going from her phone speaker all day has just played the first Christmas tune of the season. And there's 23 working days until I leave the office for the Christmas break. Hmm. Speaking of electromagnetic pulse guns, I wonder how a mobile phone responds to being microwaved at the lowest setting for a couple of seconds, without the battery in it? The trouble is, if I ask her to turn the damn thing off, she refuses, and a couple of days later the thing mysteriously fails to turn on, I'll be suspect no. 1, but if I just microwave the blasted thing I'll feel guilty I didn't give her a chance to turn it off in the first place. Better not. Dammit.
