ggunn - yep, Marla and I were there last May when you were (you gave me one of your CDs then - thanks!)
Pumba would find those crab carcasses, dance with them, wear them on his head, etc., then prop them up on a coral ledge so dive groups behind us would be fooled into taking pictures of this live crab until they see the pics later and realize there was a big hole in his shell.
He'll be missed around BA, but they've still got a great crew. They have a "new" Goerge ("Jorje") that was (I think) previously with Dive With Martin. We dove with this new George twice last week and he was very pleasant, cheerful, helpful, and safety-oriented. We really liked him and I think he's signed on with BA now.
(by the way, just got back last night, got to the office today, not wanting to be here, and my computer monitor is swaying back and forth due to my brain still thinking I'm on the dive boat)
