Food is funny. I heard a comic many years ago say 'Life is a Twinkie.' When there is no other way to explain some office calamity I say, 'I guess life is just a Twinkie.' I laugh off the tension, then I seriously take care of the problem.
There are lots of other funny foods like chicken soup, meatballs and Bill Cosby's favorite, Jello. If you majored in philosophy, you might find deep meaning in the Twinkie line. However, most of the rest of us would agree that the line was pure nonsense. This kind of wordplay can do wonders to jazz up a public speaking engagement, and that ain't chopped liver.
