… a four-leaf clover.
No, really. I found one while walking back from class today. I’d post a picture of it, but my camera’s batteries are busy recharging at the moment. The really unfortunate thing is that when I tried to sing “I’m Looking Over a Four-Leaf Clover,” the only words I could remember belonged to the spoof of the song that we used to sing at camp…

I’m looking over my dead dog rover,
That I over ran with the mower!
One leg is missing, the other is gone,

The third leg is scattered, all over the lawn.
No need explaining the one remaining,
The one on the kitchen door!
I’m looking over my dead dog rover,
That I over ran (I over ran) with the mower!

It’s really an unfortunate song to have in your head.
