Malcolm Hathaway was an overeager hostage negotiator in "A Jones for a Smith". When Stan gets caught breaking into Greg and Terry's house for items to sell for crack, the police arrive but then Malcolm charges in. His negotiation skills leave something to be desired, first sending in an extra child as a hostage and then giving Stan money and a plane without his request.
When Stan flies off, Malcolm declares victory and plants a big wet kiss on an unwilling Hayley before having the police open fire on Greg and Terry despite the fact that they were the hostages.
Malcolm is voiced by Rob Riggle.
