Vice President Joe Biden is clearly disgusted by Donald Trump's statements at Monday night's presidential debate regarding taxes.

During the debate, Hillary Clinton, the Democratic nominee, wondered aloud what Trump could be hiding by not submitting his tax returns. When she suggested that maybe he didn't pay taxes, the GOP nominee interjected by saying, "That makes me smart." US taxes, of course, are integral to keeping the government, service agencies, and federal benefits running.

"Does he play us for suckers?" Biden said during an appearance on NBC's "The Tonight Show Starring Jimmy Fallon" on Thursday.

"Think about it," Biden continued. "Can you think of any president you've studied, read about, or knew who would say anything like that? Name me one president who would do that. It angers me, quite frankly."

Biden explained his anger by using an example of a family in which the father and mother are both working for $50,000 each, taking care of their kids, and paying 15% of their income in taxes.

"I can't imagine why somebody would say that, like that 'makes me smart,'" Biden said. "My dad had an expression for real. When someone would say, 'Joe, I pay too much in taxes,' he'd say, 'Look, it's a small price to pay to live in this country.' I mean, just pay your fair share for God's sake."
