chocodiablo won hands down with her entry of 'Pencil'. I'm still not sure it's as good as twinkie or banana, but at least it makes sense and is a common object that anyone would know. There really wasn't much of a competition, though
littlestink's suggestion of school bus did make me think for a bit. I mean, i guess it would work if it were a school bus full of black people, but that seems sort of cumbersome. I mean, if it were a bus full of white people it wouldn't exactly fit, right?
Unfortunately, there are no prizes for winning but I'll be sure to use pencil the next time I need to describe myself at an Obama checkpoint.
