Every once in a while, Jerry Seinfeld stretches the definition of Comedians in his streaming series Comedians in Cars Getting Coffee, to be more inclusive. Of course, he occasionally does the same with Cars, and Coffee, but why complain? The results always are entertaining – as with this week’s visit with actor Christoph Waltz, who can be very funny as an actor, even in dramas. And on purpose. Here, he’s funny as Seinfeld takes him to, among other places, an IHOP.
