Sometimes it's funny to see where my last name can end up. In this case, in an old comic book, based on the Spider-Man segments from PBS' The Electric Company.
Ladies and gentlemen, I give you the supervillain known as... The Wall!
No one can stop him.
Not even Spidey.
To quote from Spidey Super Stories #8 (1975) by Tom Whedon/Jean Thomas with art by Winslow Mortimer:
"The Wall was once a happy high school student...
... with an after-school job.
Then the walls came tumbling down!
That blast turned the happy boy...
into the Wicked Wall!"
He then proceeded to "wreck Spider-Man's day off" by brazening trespassing onto the field of Shea Stadium where Spidey was watching the Mets game, complete with a little pennant and a cap. Dutifully swooping in to save the players from being knocked over by a guy who looks like a wall, both Spidey and the Wall were kicked out by the true evil of the day -- the Umpire!
"Too bad, Spider-Man."
