The moment was reminiscent of a light-hearted interaction between the two at McCain’s funeral in September, when cameras caught George Bush passing a cough drop to Michelle Obama.

“I didn’t realize at the time that anybody noticed what we were doing,” Michelle Obama later said of the exchange during an interview on NBC’s “Today” show.

“President Bush and I … we are forever seat mates because of protocol, that’s how we sit at all the official functions so he is my partner in crime at every major thing where all the formers gather,” Michelle Obama said.

Calling the 43rd president a “wonderful” and “funny man,” Michelle Obama said in October he slipped her “cough drops.”

“I will add they were old cough drops. That’s the funny thing, because they were in the little White House box, and I was like, ‘How long have you had these?’ And he said, ‘A long time, we got a lot of these!' ” Michelle Obama exclaimed.
