Over 60 takes? Why am I not surprised?
Actually, anything that isn't one continuous, seamless take probably involved multiple takes. It's much easier to put something like that together section by section, getting each part right once, than it is to get it all set up and have every section work perfectly on the same run-through. Most viewers, accustomed to viewing spliced-together movies and TV shows, will feel and assume that it really was one continuous process.
It was clever enough in the execution, although such concepts are at least as old as Rube Goldberg (and no doubt much, much older). I also think they should not have trashed pianos and televisions, though. :nono:
