As in so many other things, from summer camp to our love-hate relationship with the suburbs ("Here's to the Crabgrass") and our mania for self-improvement ("Taking Lessons"), Sherman had America's number. His finger was always on the country's pulse, or in this case, waistline.
In his "Overweight People" parody of "Over the Rainbow" his dream diet is not Mediterranean, it's Utopian. Given our country's eating habits, so are ours.
(Sherman gets a big laugh and applause with just the song's opening word, "Somewhere," because he copied Judy Garland's legendary pose of sitting on the edge of the stage, legs dangling over the edge.)
