Pointless and weird things you've bought for your dog/s?

Pointless? The 2 dozen squeaky toys I bought, some quite expensive, trying to find one he wouldn't wreck within 10 minutes. He would probably demolish the singing wobbling dog just as fast. My other dog has a plastic whale which swims around in a tub of water and squirts water at her. For outdoor use only. She also has a couple of stuffed toys as big as she is, and she's 50 lbs, that she likes to wrestle with.
