As I said, either it is totally in the '80s or in its prime in the '80s. Pac-Man (nor any of the arcade-game phenomena) was not huge until at least 1980. Ted McGinnley did not appear on Love Boat until into the '80s (after all, he is the show-KILLER, not show-starter!).
And on and on....
Sorry, it's just a pet peeve of mine when these "crossovers" are made!
In that case...
