Fantastic Floor

Fantastic Floor is a comic book.

History
Milhouse wanted a comic book "Fantastic Four", but Comic Book Guy sold him "Fantastic Floor". When Milhouse was complaining about that, as his family rented a house so they couldn't put in floors there, Comic Boo Guy told him that it's no refunds.
