Archie's Family Restaurants was a short-lived American restaurant chain based on the characters by Archie Comics.
 The facades showed Jughead Jones eating a hamburger.
 Around 1972, Archie Comics' parent company, Archie Enterprises, Inc., decided it wanted to further diversify into food service operations.
 Barbara and Gary Kovacs, sole owners of the recently founded BarKo Group, Inc., became interested in the venture and bought stock in the Archie companies.
 Consequently, BarKo received the contract to develop the restaurants.
"Bad Boy Trouble" is an American comic book story by writer Melanie J. Morgan and artists Steven Butler and Al Milgrom that was originally serialized in "Betty & Veronica Double Digest" #151-154.
 The story features Betty and Veronica (and other Archie Comics characters), and is notable because of its length (at approximately 100 pages, much longer than most Archie Comics stories) and because it was the first of an occasional series of Archie Comics stories drawn in a more realistic style.
 Also unusual for Archie Comics, the story was collected into a trade paperback edition within a month after the original serialization was completed.
 The story is based on the Riverdale High novel "Bad News Boyfriend".
