Dress Your Family in Corduroy and Denim by David Sedaris is a hilarious collection of vignettes and essays mostly covering the author’s childhood and adult life. The bits range from knee-slapping funny to poignant to sad to a tad bitter. It was a number 1 bestseller on the NY Times Bestseller List for Nonfiction.

Its the funniest thing I have read is quite a long time. There are lots of really funny authors. How many of them are funny enough to sell out a reading of their book at Carnegie Hall is another matter.
Sedaris is also a humorist/commentator on NPR (National Public Radio) and delivers his material with a wry, dead-on sense of humor. You can check out his stuff at:
