One of the interesting cultural events I have been privileged to witness during my Peace Corps service in Madagascar. One of the ways malagasy honor their ancestors. Each year ancestors' bodies are removed from the family tomb and then rewrapped in silk cloth. Like any good party, heavy drinking, singing and dancing is also involved.
Reminded me of university football games --- people having a good time drinking, tossing up friends for every touchdown... except not so much in this case. Just because you're dead doesn't mean the party has to stop.
