I don’t get the joke about Remini and a Segway.
They’re referencing Kevin James’ movie series (yes, they made more than one, and yet somehow, I have to think we’re worth saving as a species), “Paul Blart, Mall Cop”, in which he used a Seqway to patrol the mall.
I’m guessing they heard he’s difficult to deal with. One of my YouTube suggested videos is worst actors to work with and though I haven’t watched it (I get weird recs all the time, which is why I’m watching a thing about shipping container houses right now) Kevin James was the thumbnail for that video.
