10 strangest dives

A few years ago I read about an English home that was built over an
ancient well. Divers wanted to look inside the well, so, they made
their entry through a hole cut through the living room floor.
Didn't find much (an axe I think) but, it qualifies as an A-1 odd
dive.

I have made a few stange dives - once with a diver dressed up like
Mikey Mouse, inside the Epcot Centre, another would be the Current Cut
in the Bahamas (at certain times of the day you get blown through a
small channel pushed by the tide, and then a few hours later, back the
other way) and once at the Toronto CNE (think cheesey State Fair) in
front of bored audience. Other bizarre dives - a flooded Minute Man
tube in Texas, the mechanical shark inside the Edmonton Mall, and
well ... any other bizarrre dives that rec.scuba people have made or
heard about?
