What's your puppy's favorite Forbidden Toy?

What's the thing you can't turn your back on without your puppy running off with it? Mine has a few. Of course shoes and socks are fierce contenders and will never be outright ignored, and buttons are oh so enticing.

But every time I dry my hands, the second I turn away I see my puppy streak through my peripheral vision with the dish towel billowing behind her like a cape. I've decided it's because it looks like I'm giving them really good pets when I dry my hands, combined with the fact they dangle just above her head, she can't get enough of them.

Honorable mention, of course, to my battery-powered Dyson vacuum. I may have done too good a job of introducing them, I keep catching her trying to drag it into her bed with her. No idea what she would do with it if I ever let that happen, but at least she's not scared of it.
