Donald Trump vetoed some of the skits Saturday Night Live writers worked up for his guest gig this weekend because they were hot stuff and he didn’t think they’d play well in Iowa where he’s trying to stay in the lead.

“They come up with many, many skits and you pick the ones you think you like,” Trump explained to Bill O’Reilly in an interview that will air on the latter’s Fox News Channel show later today.

“There were a couple that were too risqué. Because you know, the poll just came down – I’m leading in Iowa, I want to stay leading in Iowa,” Trump simpered.

“We sit down and we look at like 30 – they have all these writers….They have 100 writers. I walk into the room, there are 100 – and they’re all about 17 years old, OK? They’re all young and all up in your face. But they come up with many, many skits and you pick the ones you think you like.”

Trump also took the opportunity to knock down GOP rival Ben Carson, who is beating Trump in some polls, by weighing in on CNN’s investigation of Carson’s claims he was violent as a child.

“He hit a friend in the face with a lock. He tried to kill somebody with a knife and he said he suffers from pathological disease. OK? When you suffer from pathological disease, you’re not really getting better unless you start taking lots of pills and things,” Trump warned. “[H]e’s trying to prove that he did it in order to have credibility. Who would want to prove this?…There’s something very strange here, there’s something very strange that’s going on.”

Asked about reports that ISIS blew up a Russian passenger plane, killing everyone on board, Trump said, “Well first of all, I’m very happy that Russia is bombing the hell out of them and it was a Russian plane. There’s no love lost there. So Russia having somebody else working that is fine with me, unlike some people. They want to do it themselves. If Russia wants to do it, I think it’s terrific.”
