I see potential for a new product.
"This year's must-have gift for the cost-conscious traveller, the Ronco In-Tube-ator. Now you can quickly refill those convenient travel-size tubes with toothpaste purchased in the economical large sizes. Simply screw the male ends of both tubes into the In-Tube-ater and transfere the valuable paste. Order now and you'll also get our Blade-Alive disposable razor blade sharpener. Don't throw those blades away!"
(discussion of "screwing," and anotomical inuendo concerning "male," and "female" components might make this ad most appropriate for late-night cable)
