A $50 cassette doormat. If it were a Maxell XLII 90 I may have considered it.
“If you have fond memories of avoiding The Electric Slide or making mix tapes of your favorite songs from the radio, you’re probably grinning like a fool at this Cassette Doormat. Designed to look like a K7 tape, this rubber doormat is ready to receive your dirty feet. Unlike a cassette tape, it will never require winding with a pencil and it will never wear down to the point of not working anymore. You can even wash it off with the hose when you don’t like the stuff that’s on it. Can’t say that about a real cassette!” – thinkgeek
