The Stash organizes an auction to help a long time customer/friend sell his comic collection for mounting medical bills. Another customer relates to one of Spider-Man's deadliest enemies.
The guys have a showdown at a local deli (who have sandwiches made for city fixtures) to see who can make the best sandwich that will represent the Secret Stash.
Kevin holds a 5km zombie run for charity that Ming and Mike agree to participate in; Walt makes a deal for an odd item containing autographs from the 1966 "Batman" TV series.
Ming gets to run the store when Walt and Mike take sick; and a customer has first issues of "Iron Man" and "Daredevil" to sell. Ming convinces "Clerks" star Brian "Dante Hicks" O'Halloran to help out.
