At a New York Mets baseball game, a mutated wall-human creature (Jim Boyd) sneaks up behind outfielder "Gumbo" Grace Ivy (Skip Hinnant) and causes him to miss a routine fly ball. The umpire (Morgan Freeman) is also knocked down. Spidey catches The Wall, but is ejected from the ballpark because spectators are not allowed on the field.
This also aired as part of the last episode of The Electric Company (episode 130B).
