Everything from the Apple Tax case to his Doonbeg resort and beyond were raised in Donald Trump's meeting with Taoiseach Micheál Martin.
Here are five takeaways from the meeting.
1. No Pharma Karma
The US-Ireland trade deficit was no elephant in the room during the meeting between the Taoiseach and US president.
Ireland's goods trade surplus with the US reached a record €50 billion in 2021, driven by a surge in drug exports to the United States, and it was brought up on several occasions.
Donald Trump acknowledged the "massive deficit" with Ireland because the Emerald Isle was "very smart".
"The Irish are smart, smart people and you took our pharmaceutical companies," he said.
However, the conversation surrounding the trade imbalance with Ireland appeared cordial rather than hostile.
While Mr Trump said Micheál Martin should count himself "lucky" that he wasn't president when US pharmaceutical companies set up shop in Ireland, it wasn't in a combative tone.
The US President said that he would have slapped a 200% tariff on their exports when those companies first decided to have their business to move to Ireland.
"I’m not upset with you. I respect what you’ve done" said Mr Trump. "I’d love to have them back, but he’ll be fighting me on it," he added.
2. Fight, fight, fight!
Speaking of fighters - while complimenting Ireland's great fighters and "tough people", Mr Trump joked he didn't want to clash with the Irish leader, the son of an Irish international boxer.
"I think your father was a great fighter?" he turned and asked the Taoiseach with genuine interest.
"He was. You’re dead right," Mr Martin responded with a smile. Mr Martin’s father Paddy was a celebrated boxer who represented Ireland at amateur level and was known as "the champ".
"Genetically, I’m not going to mess around with you," Mr Trump jested.
3. The 'Big' Apple
It wasn't long before Donald Trump took aim at the Apple Tax case, insisting it "wasn't a good lawsuit" and that the US "has a problem with the EU".
"Oh Apple’s been treated very badly," the US president told the room full of journalists.
Apple lost its fight against an order by EU competition regulators to pay €14bn back in unpaid taxes to Ireland as part of an EU crackdown.
Mr Trump said that the EU "has gone after our companies" and that Apple "is a great company".
"We lost $16bn," he said, adding that it is "a financial battle" with the EU.
The Taoiseach said that Ireland "fought them" over the case.
4. Delayed Doonbeg
The Apple Tax case wasn't the only time Donald Trump hit out at the European Union.
He also criticised the body over an opportunity to expand his Co Clare hotel.
Before he was president, Mr Trump said that he was given permission to expand his Doonbeg International Golf Links and Hotel in four weeks.
However, he attacked EU rules for delaying the decision for between five and seven years.
He said: "I got the approvals from Ireland so quickly. They were so professional.
"But I was told something that bothered me, they said you also have to go to the EU.
"And then I hired somebody and said the process will be from five to seven years, and then found out they weren't playing games.
"That was my first experience with the EU and I dropped the project. It was a very bad experience I had," he said.
He said he hopes to get to Doonbeg soon and that he will meet Taoiseach there.
5. Admiration for Irish sport
Amidst all the hot topics that came up during the Oval Office meeting, Mr Trump also took the time to express his love for Irish sports people.
"I love Rory McIlroy. He’s a very talented person," he said.
Rory McIlroy has played golf with Mr Trump on numerous occasions - in January and again three weeks ago.
Mr Trump also expressed his admiration for former MMA fighter Conor McGregor.
Mr McGregor attended Donald Trump's inauguration in Washington DC on 20 January.
Mr Trump complimented Conor McGregor saying he is "great" and "has got the best tattoos I've ever seen".
