We are opera-ing at peak efficiency.

Today, walking east on College Street (in front of the Leslie Dan Pharmacy Building [U of T, yo]), we happened to see a man coming toward us riding a bicycle (in the proper bike lane, of course). When I first saw him, I thought he was yawning; his mouth was opened; a cavernous maw. As he came closer, I heard a faint sound and, to be honest, I thought the yawn a trifle long. Then, when he was almost upon us, I realised what was happening: he was singing. A constant note. One incredibly long "oh," with a touch of vibrato in all the right places. It was magical.

Also, I really want one of these.
