This bus ad for Fitness First in Rotterdam, The Netherlands gives you the hard sell via shame. It uses a scale in the seat to display just how fat you are to everyone around.

I, for one, would be pretty pissed off if I didn't know about this thing and sat down to wait for the bus, only to notice people laughing at my weight. It's an attention grabbing ad, to be sure, but one that might just cross the line into ruining the bus stop rather than just advertising via it. But hey, if it's getting people to work out at Fitness First, it's effective. What say you? [DirectDaily via Animal New York]
