On a related note, how cheesy would Christmas-objects have to be to be cheesy for you Americans? (Would a candy-caned striped mailbox and trash-can be cheesy enough, or is that normal by Christmas-tacky people's standards?)
I don't think one could decorate the trash can, because it needs to be mobile. I'm sure this disturbs certain people immensely. But mailboxes are decorated constantly.
You should visit America over Christmas. I recommend Florida for optimal tackiness. You will probably go blind. Most people just put up some lights, a wreath, it's nice. But every few blocks, there's that one house with 14 different glowing Christmas creatures in the front yard, a life-size glowing creche, and 5 different styles of lights, all of them blinking, covering every square inch of property.
I think the south could give Florida a run for its money...
