Will Ferrell nearly killed his The Campaign co-star Zach Galifianakis by putting nuts in his breakfast burrito.

The Hangover funnyman, who suffers from a serious nut allergy, was treated by an on-set medic and luckily made a full recovery.

During an interview with U.S. TV host Jon Stewart, Ferrell explained, "We had a lot of fun. There were a lot of pranks we pulled on each other ... Zach has a nut allergy ... and so I had the craft service guy put some walnuts in his breakfast burrito and his throat closed up, to the point where they were like, 'Someone call a doctor ... no seriously, someone call a doctor!'"

"And the EMTs came and they said, 'If I had been five minutes later, he would have died.'"
