Uses for Plastic Pour Spouts From Laundry Detergent Bottles?

Has anyone come up with uses for the large pour spouts inside plastic jugs of laundry detergent? I discovered they are easily removed with a thumb and that two jugs of "empty" detergent jugs release a whole single load-size of left-over liquid laundry soap when the drip spout is removed. I also began to save them and search for uses for the thick spouts. Temporary wheels come to mind, but for what? Anything else? They're a creative design by the manufacture so I hope we can recycle them some way other than with the jugs.
