George W. Bush walked past Donald Trump and gave Barack Obama a tap on the belly as he arrived at his seat for Jimmy Carter’s funeral service on Thursday. A two-second video of the interaction between the former presidents went viral, racking up tens of millions of views.

Bipartisan buds? President-elect Donald Trump said he and former president Barack Obama “probably do” like each other despite having “different philosophies” after the two were seen chitchatting and laughing during former President Jimmy Carter’s funeral at the National Cathedral in Washington on Thursday.

The former president and once-again-future president, who are historically something less than besties, chatted it up before the service began. (Michelle Obama was not in attendance.)
