Making the most of the PC / Mac ads

I was listening to the radio, on a radio, (yes, I'm one of the few people that still do that) and this ad comes on- "Hi, I'm a PC ; I'm a Mac" .. you know how it goes.. and then this DJ's voice comes on and he says something to the effect of "Hi, did you know that both of you can listen to this station for free online, anywhere in the world, virus free...... "

I was pretty impressed. Making ads based on ads is not a new concept, but it is when there's a positive spin put on the ad, instead of something derogatory or competitive. Normally I tune out when ads are played, but this definitely caught my attention. Nice job!
