John Hillerman (the original Higgins on the original “Magnum P.I.”) played Howard Johnson in “Blazing Saddles.”
The town of Rock Ridge in the movie had a Howard Johnson ice cream parlor, where the sign outside said, “1 Flavor.” LOL!
I remember staying at a Howard Johnson motel in Goleta, California with my family back in 1972.
Ah. I wouldn’t have caught it anyway, since I had never heard of the restaurant..
I will have to pay closer attention next time I watch it ;)
