During a routine physical, O’Brien’s doctor offered to run a DNA test for him and called him two weeks later to deliver the results.

“I’ve never, ever, ever had a DNA result like this before,” the doctor told O’Brien, “and I’ve been doing this for ten years.”

O’Brien says the doctor told him “You are 100% Irish.”

“I've never seen a 100 percent anything,” the doctor told O’Brien. “I've been doing this a lot, I've seen 93.5 [percent], I've seen 96.1, I've seen 97. No one is 100 percent Irish.”

The doctor even went on to tell O’Brien that people in Ireland aren’t even 100% Irish.

“The Lucky Charms leprechaun - true fact! - 11% Spanish,” joked O’Brien.

When he asked the doctor what the results could mean, the doctor replied: “What does it mean? It means you’re inbred.”
