Davies can have enjoyed few afternoons as satisfying as this in management, condemning a Premier League side to a comprehensive thrashing as Jamie Paterson did the heavy lifting with a superb second-half hat-trick.
It seemed as though nothing could go wrong, with Djamel Abdoun ignoring instructions by taking a first-half penalty before chipping it 'Panenka' style into the net, while Reid put the icing on the cake in injury time.
That left plenty for Davies to reflect on, but the Scot - who has had tense relations with some sections of the media this season - started his post-match press conference in unusual fashion.
Singling out one reporter and referring to some previous social network comments, Davies made a curious challenge that the pair put a charity collection together and race towards a pork pie.
"Any distance, 100 metres or a 1,000 metres...you name it," he said.
There was, thankfully, more substantial on-field action to consider.
"I think someone was waiting to be hit for four or five here," he continued.
"Our play has been very good and we created a host of chances. I'm delighted with the way we played.
"I have to say we know (West Ham boss) Sam Allardyce has bigger fish to fry...we know he has injuries like ourselves.
"But before the game we were concerned, because in (Stewart) Downing and (Matt) Jarvis, (Modibo) Maiga and (Ravel) Morrison they had B£20million of talent in the front four. We had to make sure we were up for the game.
"I wish I had £20million worth of front players because they have very good players."
As for Reid, the Republic of Ireland international signed a two-and-a-half-year extension before kick-off and celebrated with a goal just before the final whistle.
"We have just agreed a contract," said Davies.
"I'm delighted to have Reidy here, he's influential and he's club captain. I've told him to lead this team to the Premier League."
Davies also addressed the future of defender Hobbs, who is on loan from Hull but has been the subject of interest from Wigan.
Hull would consider a permanent deal for the player but Davies expects him to see out his season-long loan.
Asked if Hobbs might have played his last game for Forest, he replied: "Not a chance.
"There is a (recall) clause which is for an emergency. As far as we're concerned that hasn't changed. He's still our player.
"We're looking forward to having him here for the rest of the season if that's possible.
"The player doesn't want to leave this club and that's important."
