David Buckner, professor of organizational leadership at Columbia University, passed out live on Glenn Beck's Fox News show Monday afternoon.
"You all right?" Beck asked Buckner in the middle of a discussion on government investments.
"I'm passing out," Buckner told Beck.
"Want to sit down?" he asked, before the guest fell to the floor. "We'll be back in just a second," he said, and then the show cut to commercial.
(Big thanks to HuffPost Media Monitor Aaron Perenack for alerting us to this segment as soon as it happened.)
Beck went on to say Buckner was receiving immediate medical attention.
"Everyone thought it was part of the show because this show, you never know what to expect..." he added. "He apologizes, and I'm like 'Are you kidding me, the ratings will be through the roof!'"
