But how will I warm my soup?

Replacing a monitor a few years back; the client had a huge 17" CRT.  The thing weighed about 60 lbs and could likely survive a nuclear blast.  Heck, it was probably irradiated itself and it was giving off tons of heat.  It was about 22" long and pretty much a big crate. I was replacing it with a newer flat-screen monitor, also 17", nice, slim, and cool.  The client at first was "Oh this is great, I have so much more room on my desk," but after a few moments, she said (surprised) "Wait!  You can't take my monitor."  "Why?" I asked puzzled.  "Because the new one doesn't have anywhere to warm my soup."
