Progress

My work today consisted of undoing the work I did yesterday. Thus, by diligently applying myself, I have progressed to exactly the same place I was at 4 a.m. Monday.

Heard a great physics joke:

A neutron walks into a bar and orders a beer.
When the barmaid serves it, he asks, “How much will that cost?”
The barmaid replies, “For neutrons, there is no charge”.

O those physicists!
