British comedian Lee Nelson (real name Simon Brodkin) walked up to the podium on Friday where Donald Trump was giving a speech about his revamped Scottish Trump Turnberry golf course, and began to apologize.

Nelson, posing as an employee in a Trump Turnberry pullover, said he had forgotten to hand out new red golf balls that were a part of the course's reopening.

"I forgot to hand them out before," Nelson told the crowd. "I'm very sorry, Mr. Trump."

The golf balls were imprinted with black swastikas and left to pockmark the grass around Trump's podium.

The presumptive Republican presidential nominee gave his speech surrounded by symbols of Nazism.

Nelson is familiar with public pranks. He's the comedian who tossed dollar bills in the air at a press conference for Sepp Blatter, the former FIFA chairman, soon after the international soccer organization was rocked by a huge corruption scandal.

Trump, though, was in no mood to listen. He told security to get Nelson off his property, and security pulled the comedian away, remaining golf balls in hand.
