Sorry you had to endure that, but I gotta admit I'm grateful for ham yoga.  At my gym anyway it keeps them sequestered and out of my way.  There are always some hams in the weight areas but most stay to either the easy classes or the classes that are easy to half ass like yoga.  Nothing against yoga, it's just way easier to pretend you're doing it right than a lot of other things. I just realized something though, shouldn't we say they 10% ass it or something? Half of a ham's ass is still much more ass than a normal person, so even half assing is still a lot of work.
