The best analogy I've read in a LONG, LONG time...

...comes from a Julia Moskin article on New Orleans snow cones called "snoballs" (from yesterday's New York Times):

"A snoball is to a snow cone as Warren Beatty is to Shirley MacLaine: closely related, but prettier, smoother and infinitely cooler."

Let's see that on an SAT test REAL SOON!!!!
