Donald Trump's son Eric comes in for a fair bit of criticism but it seems his latest faux pas is unforgivable.
The US President’s son failed abysmally when he tried to pull a pint of Irish ale during his father’s trip to Ireland, producing something that was more head than beer.
Eric, 35, got behind the bar on a ‘pub crawl’ in the Irish village of Doonbeg with older brother Donald Trump Jr.
But while his brother’s pint of Guinness was relatively respectable, Eric’s pint of ale was a disaster.
The brothers are joining their father on his first presidential visit to Ireland.
They received an enthusiastic welcome in the village in County Clare, speaking to locals and posing for selfies.
Eric told the crowd: "We love this place more than anything. So thank you for this hospitality. It's awesome."
"Don and I want to buy everyone cocktails tonight," he added.
Speaking from behind the bar, Eric said: "You guys are so warm to us every single time. You are truly some of the most incredible people in the world and I hope we've made you very very proud and I hope we've made Ireland very proud."
Earlier President Trump was warmly welcomed to Doonbeg where locals waved American flags and some donned the Make America Great Again cap.
Shortly after the president and wife Melania touched down at the Doonbeg golf resort, the village erupted into a celebration with ceili music and Irish dancers taking over the main street.
