Who's on first

In my recent column about the inevitable "the system is down" phone call, I made a really dumb mistake that I have been making since childhood -- I was referring to Abbott and Costello's famous "Who's on First" bit and attributed it to Laurel and Hardy.  If you showed me photos of Abbott, Costello, Laurel, and/or Hardy, I could identify each one without pause.  One of the nice things about a weblog is that it gives you the opportunity to correct yourself -- thanks to the many of you who called me on my gaffe.
