Jerry's Glasses in "The Gum"

“The Gum,” an especially strange episode even by this show’s standards, finds Kramer keeping the gang on pins and needles to placate Lloyd Braun, lest he suffer another mental breakdown and pull out of the theater re-opening he and Kramer are orchestrating. This is all a roundabout way to put a pair of ridiculously over-sized frames on Jerry and have him stumble about because of the strong prescription (since Lloyd is under the assumption that Jerry wears glasses).
