If This Was a Joke, It's More than a Week Late

The strangest thing happened to me yesterday.  I underslept.

I woke up, shaved, got dressed, ate breakfast.  You know, the usual.  When I went back upstairs to brush my teeth & make my bed, my alarm clock said the wrong time.  It had to be.  I looked at two other clocks in the house.  Nope, my alarm clock was right.  I had woken up exactly one hour early.

Clearly, someone must have reset all the clocks in my house while I slept.  That must be it.  The alternative is that I played an April Fool's joke on myself, and that can't happen.  Right?
