GRIMSBURG: In order to win this year's Undies Award for best undercover operation, Flute infiltrates the Preggo crime family as Roberto Stanlitucci. But when Flute hits his head and believes he actually is his undercover character, Summers decides not to report it because "Roberto" is the friend he's always wanted Flute to be. When the detectives overhear Martinez talking about a budget surplus, they conspire to spend it on their own strange indulgences in the all-new “The Undies” episode of Grimsburg airing Thursday, June 5 (8:30-9:00 PM ET/PT) on FOX.
