The fun part would be someone having a heart attack, they would be in a deep deep shit because of this silly kind of advertisement...
or when the person is really wanted ;D. I would go to a bathroom when the cops show up, wait at the door, take them out, take their uniform, go outside and kill liam neeson so he can't catch me.
Whahaha that is pretty awesome. xD The first girl really did have the best reaction and nobody freaked out as much as I thought they might.
