Norwich scored five second-half goals as they thumped 10-man Huddersfield.
Terriers’ defender Murray Wallace was dismissed early on after bringing down Cameron Jerome, but it remained goalless until Bradley Johnson scored from close range just after the break.
Headers from Nathan Redmond, Johnson and Jerome extended the lead.
Substitute Lewis Grabban raced onto Wes Hoolahan’s through ball to complete the rout, with the visitors restricted to only a couple of half-chances.
The win lifted Neil Adams’ Canaries to within two points of the play-offs, while Huddersfield – who have only won two of their last nine games – slipped to 17th.
Norwich, who had only won one of their last eight home games, had their task made easier on 17 minutes when Wallace was shown a straight red card by referee Mark Brown.
A high punt forward was mis-controlled by visiting skipper Mark Hudson, allowing Jerome to latch onto the loose ball and he was through on goal when he was fouled by last man Wallace.
However, it took until 44 seconds into the second half for the home side to break the deadlock as Gary Hooper skilfully pulled the ball back for Johnson to tap in.
Two minutes later Norwich doubled their lead as Martin Olsson’s cross was met by half-time substitute Redmond, who nodded into the top corner.
The third goal in five minutes had a touch of fortune about it as Jonny Howson’s blocked shot fell perfectly to Johnson, who headed in his second.
Hooper’s flick found Huddersfield-born Jerome to make it 4-0 before ex-Bournemouth striker Grabban fired the ball high into the net just seconds after coming onto the pitch.
