What is Cheese Weasel Day, you might ask? Each April 3rd (yes, it was yesterday, but yesterday was Sunday) is Cheese Weasel Day, an invented holiday (as opposed to Groundhog Day, which has some vague, shadowy historical roots). Each April 3rd, the Cheese Weasel -- and I'm not making this up -- visits every IT person on the planet and leaves a slice of cheese under his or her mouse. I suggest checking under yours...if you missed it, best to catch it now rather than three weeks from now. Essentially, the Cheese Weasel is the Easter Bunny for techno-geeks. There's even a Cheese Weasel song (tune unknown).

In the meantime, Happy Cheese Weasel day. May you be blessed with camembert or room-temperature stilton rather than Cheez-Whiz.
