Whales in Sacramento river

If you haven't been in a cave somewhere, you probably know there have been two hump-back whales in the Sacramento River. They've been trying to lure them back to the ocean. The most popular method is to play tapes of other whales. They said it was tapes of other hump-back whales eating, and it chased them the other way.
Okay, am I the only one thinking, a translation of the tape says: "Get away from me, I'm trying to eat!" or "You touch my food and you'll draw back a nub!"

Well, you gotta admit, I fought back the temptation to write this for quite a while. The whales are almost home free.
