I took this to Best Buy for some fun. The only downside was the MASSIVE amount of interference in the store, which caused all the stations to have static. Despite this, I waved my hand over radios, asked clerks if the TV's had radio built in, touched 2 CD's together, pressed the X button on the PS3 and asked what was wrong with it, turned the knob on every appliance, etc.

Never gets old. My GF wanted to kill me.
