No clue...

I don't know, I think it means you should invest in screened windows, but the universe really wants me to think of magpies lately. Earlier this morning/last night I read someone saying in IRC that magpies like to attack bicyclists where he lives, and then like an hour later I saw a video on Twitter of a magpie attacking a kid on a bicycle, and then this question. First time I've ever heard of magpies attacking anyone on a bicycle, or attacking anyone in general, and first time I've heard the word magpie in years.
