Of that I am well aware, but I do seem to recall Mosher himself making a M*A*S*H reference recently in of the threads where WIM was being massively made fun of.
Besides, the lemur dance is done to "move it," so I changed the lyric slightly as a tribute to Mosher, not as a reference to dancing in a mosh pit. Still, you could argue that the lemurs are pretty good moshers themselves...
