Books Defaced By Strong Bad
From Homestar Runner Wiki
Strong Bad sometimes ruins books, saying they're his. He has done this a few times now:
Strong Bad Classics! (He ruins the ocelot and the porridge maiden)
Sbemail: kids book (He ruins Everyone Is Different, by Lem Sportsinterviews)
Strumstar Hammer (easter egg in kids book) (He ruins the original book)
