The line comes from Blackadder, the BBC historical sitcom starring Rowan Atkinson as the scheming Edmund Blackadder and Tony Robinson as his filthy, long-suffering servant Baldrick. The show, which aired in the 1980s, became famous for Blackadder's elaborate Elizabethan-style insults, and this breath jibe is a prime example. Clipped for soundboards, it circulates among British comedy fans as a go-to roast, surviving because the writing is sharper and ruder than most modern sitcom put-downs and instantly signals Blackadder's voice.
