And our 1D fellas might have panicked a bit, but at least you know they take scary situations seriously.
Watch the full video of the Ant and Dec One Direction prank below!
Dec, playing a 1D fan, suffered a fake asthma attack, which seemed serious enough to the 1D guys that they called for an ambulance. Ant was a TV reporter in the sketch, as he explained, "The ruse was that 1D's biggest fans had flown in to meet them. Dec dressed up as one called Jack from New Zealand and I was Ben, a TV host from there."
He added, "I introduced him to the group--and the meeting didn't go as planned. But they fell for it."
Dec explained his role, saying, "I faked an asthma attack. They panicked and I hyperventilated. They called medical emergencies. It was such fun and they fell for it. We did it in Madison Square Garden before Christmas."
You may recall Louis and Zayn pulling a prank involving a pregnant woman on Harry, Liam, and Niall.
Was this a mean trick--or pretty funny?
