In Roger Welsch's book "Diggin' In and Piggin' Out: The Truth About Men and Food" he tells about tossing some leftover lutefisk out in the yard for his two Labs, Lucky and Thud. He says "I thought they might like it. They eat cow poop, for Pete's sake. I tossed the fish into the yard. The dogs sniffed it, circled it, sniffed again, and then...then I got a new assessment of exactly where lutefisk stands on the gastronomic scale: they rolled in it."
