who are these people?

Last night I was walking down a pedestrian street with some friends and saw two guys transporting a queen sized mattress by laying it across a grocery cart...watching them try to reach the handle and steer this down the street was amusing to say the least...if only I had my camera with me. I can't help but think of the Seinfeld bit where he talks about how men are always trying to be like superheros...transporting mattresses on top of tiny cars and imagining that by sticking their hand out the window it will hold the huge mattress secure while they drive on the highway. There must be a better way...
