He was in the Police Academy movies, but I never saw them. I still remember him from this stupid but insanely funny “magic” act he used to do on variety shows in the 1960s and 1970s
I didn’t even need to click the video. I saw the name and that stupid tune was instantly in my brain. RIP.
In memoriam:
The man could make a marshmallow magically disappear in seconds!
RIP, Art. 
Funny how we have little “boxes” we put some actors in.
To me, he’ll always be Moose, the truck driver teamed with Rosie Grier’s Benjy in Movin’ On. But I looked at his IMDB credits, and he was in a ton of stuff I watched.
It never occurred to me that the finger magic guy was the same guy who played Captain Mauser.
