I'm not sure if this has been discussed before, as a cursory google search only turned up hopes for a Moo Hoo Man appearance on these boards, but I've found a tombstone in 203 right next to (and nearly invisible as it is hidden by a cart) the Sobrero tombstones which says
"Moo Hoo Man. 1972-1978. Peace at last."
I don't know who Moo Hoo Man is, I don't get the reference at all, but I figure someone will take solace in this discovery considering all the hopes and speculation about it. If this has been posted before I apologize.
