Full House and Boy Meets World are two of the greatest TGIF sitcoms of all time. The comedies are still watched by many fans today thanks to streaming, and they both had successful revivals. While Boy Meets World began towards the end of Full House’s run, the two shows are considered to be among the best sitcoms of all time. Their successes and shared network may not be all that they have in common, though, as the internet is debating a theory that they’re in the same universe.
