Blades' stunner; Sheff Utd 4, Birmingham 4.
He had seen his team go 2-0 down then 4-2 up before finishing level.
Birmingham skipper Steve Bruce said: "The supporters must have enjoyed it. They certainly got their money's worth.".
But some of the goals could have come straight out of football's It'll Be Alright On The Night, with these Division One title favourites playing as if defending was going out of fashion.
Paul Furlong and Mike Newell fired Brum ahead only for Gareth Taylor to pull one back on 45 minutes.
Then came six manic minutes in the second half when United scored three times with two from Andy Walker and another by Taylor to take a shock lead.
Paul Devlin, from the penalty spot, and Jonathan Hunt made it 4-4 to atone for earlier misses that might have sewed the game up.
Birmingham boss Trevor Francis said: "We showed real spirit. Not many teams would have recovered after being hit with three goals like that. But we should have done better at the back and we missed chances too."
