The Irish star scored against Leeds last season, Coventry in the Carling Cup in September and now a treble against the men from Molineux, where he made his name as a 17-year-old. Let's hope one day we play Inter Milan in Europe!
It has to be said though that this wasn't a five-star performance overall but we looked dangerous every time we went forward, particularly in the second half.
Spirited Wolves will point to a glaring miss from Henri Camara with the score at 2-1 - an equaliser there would have made things interesting, not least as we went 3-1 up within a couple of minutes.
But was Keane's day with Fredi Kanoute adding his eighth goal in eight games and a stunning strike from Stephane Dalmat in injury time the icing on the cake.
The first half wasn't the best and there was frustration in the air when we went in on level terms.
Keane put us ahead after 27 minutes but we were caught by the classic sucker punch just over a minute later and missed two great chances to forge ahead.
Dean Richards missed the first of those chances after five minutes. Still up from a corner, Darren Anderton picked out the big man at the far post and although he controlled impecably, Michael Oakes was out to smother the chance.
The opener arrived after 28 minutes. Anderton and Stephen Carr created space out of nothing on the right touchline, Anderton flicked to King who lobbed the perfect through ball to Keane - his finish deadly.
That should have been the platform but Wolves levelled with the celebrations barely over. It wasn't the best of goals with the ball bobbling around and Paul Ince managed to fashion a shot on the slide that nestled in the bottom corner.
The best chhance of the half fell to Keane who somehow failed to connect properly from close range after a splended one-touch move completely opened up the visitors. The look on Keane's face said it all.
We needed an early goal after the break and it arrived within five minutes. It was
simplicity itself. Anderton took a quick throw, got it back from Carr and his excellent first-time cross headed home by Kanoute.
The French striker almost repeated his wonder goal against Everton from 35 yards but Oakes was alive to his dipping volley.
Wolves fought back and should have capped their best spell with the equaliser after 72 minutes. Sturridge showed pace down the line to get away from Richards and Taricco, sped into the box and squared to Camara who managed to scoop over from six yards.
Two minutes and Keane put us 3-1 up, guiding his volley from Paul Konchesky's deep cross into the top corner and 10 minutes later he bagged the matchball, tapping home the rebound after Oakes palmed away Anderton's close-range header.
Wolves bounced back again within a minute, Rae steering home across Keller but Dalmat saved the best until last, picking up Carr's pass, driving through two defenders and smashing into the top corner.
