VIDEO: The best of Joe Biden at the Senate swearing-in ceremony

The Onion's favorite vice president was all smiles and jokes at Thursday's mock swearing-in ceremony for new senators. Every inch the avuncular politician, Joe Biden shmoozed and flirted with the new men and women of the Senate, their children and especially their moms. Among other moments, Biden asked Claire McCaskill if she planned to get "a lotta machine guns" to protect her daughters, and he told Sen. Heidi Heitkamp she was about to be frisked. "Spread your legs!" he said. "Need any help on your pecs, lemme know," he told one of Sen. Tim Scott's brothers.

Here's a compilation of Biden's best moments, courtesy of Talking Points Memo:

"You're going to save that picture," Biden told the family.
