My favorite ever was I think during Hurricane ... oops I mean Superstorm ... Sandy. Some public official was giving a conference and the sign language guy was suitably over the top with expressions but in the middle of it he seemed to get in a sign language fight with someone in the audience. It really got nutty while that was going on.
The sign language guy was being heckled??? Sign heckled??? Oh, man, that must’ve been priceless.
