Jonathan "Johnny Tightlips" Schmallippe, voiced by Hank Azaria, is a member of the Mafia and associate of The Springfield Mafia.
He says very little, which spares him from accusations of being a "squealer," but his reticence tends to be unhelpful to himself or others. He is assumed to be a similar character to that of Clamps, from the brother show of Simpsons, Futurama.In "Insane Clown Poppy", there is a shoot-out in Fat Tony's mansion and Tightlips is shot by accident. When asked where he's injured, he says " I ain't sayin' nuthin'!", and when asked what to tell the doctor he says, "Tell'em to go suck a lemon."Johnny Tightlips is a reference to Frank "Tight Lips" Gusenberg, who was shot down in the real-life St. Valentine's Day Massacre in Chicago and replied "nobody shot me" while dying.He was seen shooting Frankie the Squealer (see below) in Reaper Madness (he wouldn't die since Death was killed by Homer's Bowling Ball).The German word "Schmallippe" translates to "tight lip."
