Marvin's Marvelous Mechanical Museum 

A museum in Michigan which is dedicated to displaying a variety of animatronics and other coin-operated machines. It was originally owned by the late Marvin Yagoda, until he died just after New Year's of 2017, when ownership was transferred to his son, Jeremy Yagoda. Due to the COVID-19 pandemic, the museum was forced to shut down temporarily, until Michigan reaches Phase 5 of containment, and was faced with financial trouble due to maintenance on the machines, but thanks to a GoFundMe, they were able to remain afloat. Though Marvin died in 2017, he is attributed with the quotations "Wouldn’t the world be better off if we took nonsense more seriously?", and "Don’t use time or words carelessly; neither can be retrieved".

Furthermore, the "fabloo" band known as "Tally Hall" created an album named after Marvin's Marvelous Mechanical Museum, and Marvin himself appeared in an episode of the Tally Hall internet show

Person 1: I heard there's this one place with some sort of weird robots and stuff down on Orchard Lake Road, called Marvin's Marvelous Mechanical Museum. Anyone wanna come with me?

Person 2: Sure, I think I heard some neat stuff about it online
