I'm not saying I'm as bad as Howard Hughes, but I will confess to always tearing a bit of toilet-roll of paper towel off and using it to open public bathroom doors on my way out.
At $US50 a pop, these Toepeners would surely end up saving shopping centres, offices and other public venues money over the long run, with less paper wasted and thrown on the floor. Not to mention the debt to society they owe, with 999,999,999* different types of germs transmitted on bathroom handles every day. Public bathrooms of the world, please unite and buy a Toepener or two now! [Toepener via Marginal Revolution via OhGizmo]
*I could've just made that stat up. But I wouldn't be surprised if it were true!
