Yes, an old goldfish CAN be taught new tricks!  Gosh, who’d a thunk?  Here’s what the catalogue copy says:

I would have thought this was a total gag gift except for this YouTube video.  Take a look.  They claim that, “No stunt fish or special effects were used; that was an actual fish trained using this kit. You get everything you need to teach your fish to play football, play soccer, limbo, weave, fetch, go through tubes, and more! And then you can quit your job and go on tour. It’ll be just you, Twinkie the fish, and the open road. With the R2 Fish Training School Kit and a little perseverance, the world is your oyster . . . well, goldfish.”

But can they teach their fish to shake fins?  I think not.

Anyway, if you’d like the best trained fish in your town, you can buy the kit for $29.99 here:
