Missy and Mussy are very messy sisters. Their dresser drawer consists of 43 white socks, 2 black socks, 23 blue socks and 8 red socks. What is the minimum number of socks they must remove from the drawer to be certain they have four socks of the same color?

They already have more than four of two colors. Why remove any? Do they want ONLY four of one color? If so, then remove four red.
What does this have to do with geometery?
