Trinity College may have reminded them of Hogwarts, but the Obama children looked like they would have preferred to be at a Harry Potter theme park than poring over dusty documents showing their distant Irish heritage.
The glazed over expressions on the faces of Malia (14) and Sasha (12) during their brief visit to Ireland with First Lady Michelle Obama didn't go unnoticed by the US media.
ABC's Good Morning America featured a segment with the reporter noting that "Even the president's daughters can get a bit bored with history" as they were shown the Book of Kells.
It played a clip of Mrs Obama saying they were "thrilled" to be at a private Riverdance Show in the Gaiety Theatre, with her daughters shown in the audience rubbing their eyes, apparently drowsy after watching another of their parents' speeches.
The ABC news reporter referenced 1980s Chevy Chase movie National Lampoon's European Vacation, where teenagers are bored by the sights of the continent saying: "As they meet with distant Irish cousins how quickly these once in a lifetime experiences can take a turn when the children become about as impressed as the Griswalds".
After the report, anchor George Staphanopoulos quipped: "Oh man, lunch with Bono again?"
RTE News presenter Bryan Dobson later picked up on the Obama daughter's apparent boredom, tweeting: "#spareathoughtforthekids a genealogy lecture, the Book of Kells, Glendalough, a pub lunch with Bono! What was your worst childhood holiday?" He later suggested the girls might have visited Tayto Park instead.
