The president-elect said he "didn't realize" one thing about the exchange at Jimmy Carter's funeral until he saw footage of it.

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.)

Former first lady Michelle Obama didn't attend the state funeral for former President Jimmy Carter. Except for Michelle Obama, all of the living former presidents and their spouses were at the funeral Thursday.
