What is the stupidest invention you have ever seen for sale?

I remember a product called the E-Z cracker, a device that would crack your eggs for you. The commercial showed people dropping eggs everywhere and smashing entire shells into their pan. I can crack an egg with one hand without a bit of shell infiltrating my cooking apparatus - is this thing really necessary? 😆

So, what ridiculous “As Seen On TV” infomercial products have YOU seen?

Tickets to Mars.
