Luton Town stunned record-breaking Middlesbrough boss Neil Warnock with three goals in five sensational minutes to steal all three points.
Taking charge of his 1,602nd game in league management, to beat former Crewe boss Dario Gradi's mark, Warnock had never suffered defeat in 12 previous meetings against the Hatters with all his previous clubs.
But the 13th proved unlucky despite going in 1-0 up in the 15th minute after youngster Josh Coburn slid in at the far post to connect with Andraz Sporar's low cross.
Luton levelled on 57 minutes when skipper Sonny Bradley headed in James Bree's corner.
