Obama's booster was Scott Van Duzen, owner of the Big Apple Pizza & Pasta Restaurant in North Palm Beach.
"Everybody look at these guns," Obama said of Van Duzen's arms, according to the White House pool report. "If I eat your pizza, will I look like that?"
The pool report also noted Van Duzen said he can bench-press 350 pounds and feels "comfortable" with the president — literally.
"I don't vote party-line, I vote who I feel comfortable with, and I do feel extremely comfortable with him," Van Duzen said.
"One of the reasons that we wanted to stop by is that Scott has been doing unbelievable work out of this pizza shop in promoting the importance of donating blood," Obama said, according to the report. "And so he has set some records here in Florida. He has received commendations from the White House, the surgeon general, he has galvanized and mobilized the local community and he's educating kids and folks all across the country on this issue. So here's an example of somebody who is doing well but he's also giving back. So we just want to say how proud we are of him. I still wonder how he got these biceps, but what we know is that the guy's just got a big heart along with big pecs. So we're very proud of him and we just want to say thank you for all the great work."
