I have a theory, just something that occurred to me really. The potential source of all those random socks that seem to have no partner in your sock drawer: Sock babies. Yes, I said sock babies. Think about it, we all joke about makin sock babies (jerking off in a sock to keep the mess contained), but in reality they exist and explain how we can have a drawer full of paired socks, yet still accumulate a pile of mis-matched socks. Those extra socks are really your illegitimate sock children!!!
