Who's Magenski?

I’m not sure of the spelling but it’s pronounced

Ma-jen-ski

I heard this first on an old “Burns and Allen” show, George says something about Magenski and Gracie says “OK but I’ll just have a small glass.” (laughter)

Tonight I was watching “The Three Stooges,” and Larry is struming a guitar and Moe says “Hold it Magenski”

Anyone have any idea who this guy is?

Could they be saying Nijinsky?

That’s possible, thanks for the lead
