I am not, as Dave Barry would say, making this up -
Scientists at the Berlin Zoo have been experiementing with mood music to encourage the sharks to, well, fornicate more frequently. (As long as these sharks stay inside their tanks inside Berlin, I have no problem with this experiment.)
Appaerntly one of the songs which sharks find most conducive to procreation is Joe Cocker's "You Can Leave Your Hat On" immortalized in the soundtrack to 9 1/2 Weeks.
The Indianapolis Zoo has a new shark petting tank. I am deeply tempted to bring in a boom box... though I would not dream of turning it on while petting them. Perhaps I should donate some ipods?
