S.P.U.D. was at first an accident, like most of Slog's recipes. One night in 1909, while out on safari in New Cackalack, trying to bag and consume his first gorilla, Slog cooked up some grub for himself and his three hillbilly guides. He had fried up and seasoned some not particularly offensive pig brain and potatoes in a cast iron skillet over a fire. A gorilla was spotted right as they were about to partake in the meal and the four men rushed off, guns in hand, on a wild goose chase that lasted clear through till morning. When they arrived back at camp, empty-handed and exhausted, five hours later, their fire had died and the cow brain and potatoes had cooled. Now, a pig brain is about 60% fat, so most of what was left was a bunch of potato chunks stuck in a congealed, greasy mess, and much of the actual brain matter had been picked by scavenger animals. Rather than waste the food, as would be heretical to Slog's lifelong creed, he stoked the campfire again and brought it to a high temperature. What resulted were greasy, fatty pucks of potato, of an almost hashbrown-like texture, with tiny bits of brain matter and sweetbread. It was delicious. Slog knew he would take this idea all the way to market.
