I hate pointless information. Today I saw this icon on my calendar, next to a vacation day I had scheduled for yesterday (Wednesday 06/11):

Everything was fine until I thought to myself, I thought, "what's that little guy waving his hand for?" So I moused over the icon, expecting meaningful information, but alas - the little person waving his hand icon simply popped open a context label that read: "Person waving hand Icon".

C'mon. Really?
