I had a weired dream last night. In the dream I came up with an idea of selling twin packs of hair dyes for family with twins. They can dye their babies' hair into different colors (say bright green for one and light purple for the other) so it is easier to tell them apart. The business was very successful and everywhere you go you can see a pair of babies with contrasting hair color in twin strollers.
The dream was weired (but sounds like a good idea). :)
