Jamison Gibson-Park says Ireland's victory over England is "right up there" as a career highlight, even if the visitors had to dig deep to beat a team with 14 men almost right from the kick-off.
However the history books will record it as a Six Nations victory for Ireland at a venue where they have struggled so many times in the past.
The cherry on top is that the 32-15 triumph was the largest margin of victory recorded by Ireland at the home of English rugby.
Despite some major question marks placed on the scrum, the lineout and Ireland's wasteful nature in attack, a record win is a record win.
"It's right up there, man," said Gibson-Park, who was among the visitors' best performers.
"Obviously we had the disappointment of France a couple of weeks ago and we took a lot of lessons from that, me personally as well.
"We implemented a few of those and are glad to come away with the win. But it's definitely right up there in terms of the scale of game and how big it was for me, for sure."
All last week head coach Andy Farrell, skipper Johnny Sexton and a numerous players spoke of the need for Ireland to pick up a major scalp away from home, something that hadn't been achieved since Joe Schmidt's era.
And now it has happened. "It's obviously something we've spoken about as a team that great teams go away and win," said Gibson-Park.
"We hadn't really done that. We had the disappointment of France and we knew how difficult it was going to be coming to Twickenham.
"I don't know whether it's a monkey off the back but we're delighted to get a big win away."
The scrum-half added: "We obviously knew how tough it was going to be to come here to Twickenham and win.
"It's probably one of the toughest challenges in rugby so we were under no illusions as to how difficult it was going to be.
"Unfortunately for England they went down to 14 early but credit to them they stuck in the game, as we expected them to.
"We all know that when teams go down to 14, they tend to lift a bit. I've been on teams where that has happened.
"They put in a pretty awesome performance considering they were down to 14. Kudos to them but we're obviously happy to come away with the win."
Ireland led 15-7 at the interval thanks to tries by James Lowe and Hugo Keenan but England drew level in the 61st minute as they turned the screw at scrum-time.
The vocal England support in the stands roared on their side as they sensed the tide turn in their favour, but Gibson-Park insists that didn't affect the Ireland players who managed to produce two late tries to secure what could yet be a crucial winning bonus point.
"We just tried our best to stick to processes and stay calm. It can be tough when there are 80,000 screaming fans," said Gibson-Park.
"In fairness to them they stuck in really well and scrambled well in defence, put us under pressure with their kicking game and luckily the last 10 or 15 minutes it might have caught up on them a little.
"We ran in a couple of tries and came away with the win so we're happy, obviously."
What Ireland could do with next Saturday night is a favour from England now. The men in green's aim is to beat Scotland at home (kick-off 4.45pm) before England face Grand Slam chasing France in Paris (kick-off 8pm Irish time).
If Ireland win and the Red Rose were to do the same, Ireland could secure the Six Nations title to go with the Triple Crown.
"Yeah, for sure, man," said Gibson-Park. "That's out of our control now, so we just have to do our best to beat Scotland next week."
