Why does your nose only itch when both hands are full?

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Just like you how end up in the longest wait line or in a traffic jam: because you don't notice it otherwise.
That one actually has a simple math reason: the slow lane is slow generally because it has more cars, so more people are actually in it than are in a faster lane. (Ignoring traffic waves and taking the average speeds)
