It's part of politics, kissing babies, but one particular infant didn't get the memo when outgoing Vice President Joe Biden went in for a smooch.

The 10-month-old, who belonged to the family of Sen. Richard Burr, R-N.C., went for the head fake as Biden leaned in and cooed.

The vice president recovered from the rejection by carrying on in a whisper with Burr's granddaughter. 'We're having a conversation,' he told the family, as the child squeaked out a cry.

This was one of the handful of memorable moments from today's swearing-in ceremony in the Senate, in which the veep – with only 17 days in his term left – lived up to his reputation as 'America's uncle.'

HEY BABY: Vice President Joe Biden tried to make nice with a baby belonging to the family of North Carolina Republican Sen. Richard Burr

The vice president went in for a smooch, but missed his mark, as the baby bobbed her head forward seeming to care less

Not accepting the rejection, the vice president continued to whisper at the small child, telling the family 'We're having a conversation!'

The Senate Chamber is used for the official swearing-in ceremonies, but Senate rules limit cameras, so the vice president does the whole thing again with the families present and poses for pictures after each senator comes through.

Today Biden found himself striking out with some of the children.

Besides the head-faking baby, two-year-old Abigail, the daughter of incoming Sen. Tammy Duckworth, D-Ill., didn't look so pleased when the vice president came in for a tickle.

'How you doing Abigail. She's saying "when's this over, Mom?"' Biden said as the little girl rode in on her mom's lap as the military veteran rolled up in her wheelchair.

Relations between the toddler and the veep warmed up later as Duckworth asked her daughter to blow the vice president an air kiss.

She did and the vice president blew an air kiss right back.

Vice President Joe Biden was also rejected by the two-year-old daughter of Sen. Tammy Duckworth. He went in for a tickle. Abigail, Duckworth's daughter, wasn't impressed

Biden also brought out his famous 'finger guns' and instructed several sons and grandsons of senators to 'keep the boys away from your sister.'

'Who's got the camera? Who's got the selfie camera?' he remarked as he made Sen. Richard Blumenthal's family crouch together for a selfie.

When it was Sen. Marco Rubio's turn, Biden decided to push the Florida Republican and former presidential contender out of the frame momentarily, so he could just pose for a picture with Rubio's four young kids.

He occasionally got political too.

When he saw Sen. John McCain, R-Ariz., re-elected for a sixth term, Biden uttered, 'Thank God, you're here John.'

McCain, along with his Senate buddy Lindsey Graham, R-S.C., has already been putting pressure on President-elect Donald Trump over the future White House occupant's cozy relationship with Russia and unwillingness to connect the Kremlin with the election year hacks, which mainly targeted Democrats.

'I'm so glad you ran again, I really am,' Biden told McCain, as a testament to their across-the-aisle friendship.

In another show of bipartisan support, when Biden saw longtime Sen. Chuck Grassley, R-Iowa, and his wife, he smooched Barbara Grassley right on her lips.

And in another, he made up a creative compliment for Sen. Richard Shelby's wife, Annette.

'You're not vertical, you're beautiful,' Biden told the Alabama Republican's spouse.

'I'm the only Irish man you're going to find that doesn't drink,' he told members of Sen. Patty Murray's family.

'I'm kind of boring,' he added.
