I have an assignment for Econ 201 in which i have to come up with an economic conundrum and then solve it. This is based on Robert Frank's the economic naturalist and steven levitt's Freakanomics. One example was the question of why pop and water are usually sold in round bottles at a convenience store or gas station but milk came in the square cartons. The answer was that the pop and water could be stored anywhere but milk had to be kept refrigerated so they wanted to maximize the amount that could be stored in the fridge so there would be less wasted space and therefore less wasted money.

I am having trouble coming up with a conundrum of my own. Any ideas? (and for anyone who has read either of the two books above, we are not allowed to use anything from them)
