The late-night host also answers questions about day-drinking with Kelly Clarkson and his one-on-one interview with Kanye West.
When the "Late Night" host stopped by "Watch What Happens Live" Wednesday night, he told Andy Cohen, "I was shocked because I feel like a couple that agrees to buy a pig together has a deep, abiding -- I mean, again, both people in that relationship have to think a pet pig is a good idea. And you would think that means you have a lot in common with somebody."
Meyers actually interviewed Davidson about Piggy Smallz last month right after the then-couple first brought him home. Now, custody remains with Grande.
Meyers also answered an array of fan questions, including whether he was actually wasted that time he went day-drinking with Kelly Clarkson on "Late Night with Seth Meyers." (Please feel free to relive that glorious video below.)
"I drank so much in the two hours we did day-drinking that I said goodbye to her twice," the comedian revealed. "And then after she left, I went to my producer and said, 'I feel terrible! I forgot to say goodbye to her.'"
Another fan asked the comedian, "Is there anyone you expected to be a total dud as an interview, who turned out to be really good?"
"It's hard to answer this question without admitting I thought someone was a total dud," Meyers replied. "I will say this -- it was only my second show, and I didn't think he would be a total dud. Kanye West was a fantastic interview, genuinely, because he -- everybody on talk shows -- I think in the back of their head, they're also thinking, 'Oh, I shouldn't say exactly what I think because this is on television.' And I don't think he thinks that way, so you get a very good, honest interview."
A third caller asked Meyers if he had a favorite joke about President Donald Trump. He replied with a grin on his face.
"Donald Trump says he's a friend of the blacks, but unless the blacks are a family of white people, I bet he's mistaken," Meyers replied laughing.
He was also forced during a game of "Plead the Fifth" to reveal what he thought was the "DILFiest" thing about Trump.
After some contemplation, Meyers replied, "I guess I like the muffining of his belly over his slacks."
