At least this guy had sense enough to keep his clothes on.Tilikum, the SeaWorld Orca who killed trainer Dawn Brancheau on Wednesday, already had one murder to his credit during his time at Sealand in Victoria, B.C. Now we find out this is his third time at the rodeo:Tilikum came under the spotlight again in July of 1999 after a man was found dead in his pool. The man, who apparently stayed after park hours and evaded security, was found naked in the pool.So just to review. Don’t: break into SeaWorld, strip off all your clothes and go nightswimming with the pretty whales with the funny name. Check.
