Bob Beckel, Democratic political mind and co-host of Fox News' "The Five," had a slip of the mouth on-air last evening when debating about tax cuts.

Apparently, Beckel was so appalled at the notion that his conservative co-hosts want more tax cuts, that he couldn't contain himself. His brief verbal outburst went as follows:

"You gotta be so full of s**t," he said. "I can't believe--"

Even Beckel was surprised that he went so unhinged. After a commercial break (and after his fellow co-hosts told him to watch his mouth), he said:

"I apologize for a slip of the tongue. I don't think I said it, but if I did I apologize."

Watch it, below:

As the Huffington Post notes, this may be the second time Beckel has cursed on-air. Watch the following video from earlier this summer:
