David Letterman has been in the news for all the wrong reasons of late. With his adultery and extortion scandals still fresh in the minds of many Americans, it’s best to look back at the golden age of the Late Show, when trips to Drew Barrymore’s flashing antics were about as controversial as things got. My personal favorite segment has always been Stupid Pet Tricks, which partially explains my fascination with gimmicky pet gadgets.

I found a product online just the other day that’s meant to turn regular everyday goldfish into swimming party tricks. The set includes a soccer net, a tiny ball and even a limbo bar. Like most animals – including marine life – goldfish are food-driven. They have famously short memories and nonexistent attention spans, but it’s possible to get them to do almost anything for the promise of some fish food.
