The line comes from Eric Morecambe, one half of the British double act Morecambe and Wise with Ernie Wise, whose television shows were a staple of British comedy in the 1970s. Morecambe often played the bumbling showman, delivering throwaway boasts with total confidence. The phrase became one of his familiar catchphrases, used when presenting something as perfectly finished. Clips of the duo still circulate online because the delivery is instantly recognisable, and modern editors reuse the short line as a ready made punchline for edits, fixes and transitions that are meant to look invisible.
