It's the most prank-filled competition ever as Guy Fieri asks the judges and son Hunter to select the unappetizing whammy ingredients that the all-star competitors must use to make an appetizer and entrée. Then, Guy declares a chef swap, and the judges find themselves cooking with the whammy ingredients they chose, and Hunter discovers that he'll be competing against all-star chefs. In a final twist, Guy takes a seat at the judges' table.
