Bugs marketed as features: diet fork

I found out from FARK about a diet fork with the following features:

• Shorter and dulled teeth inhibiting user from grasping larger pieces of food at any one time
• Smaller triangular shaped surface area allowing dieter to hold less food than many other forks
• Uncomfortable grip compelling user to put fork down between bites, slowing the user's eating speed

This appears to be a real product, available for purchase.

A cliché of the software industry is "That's not a bug, that's a feature". (See, for example, the jargon file.) While normally limited to software, this equivocation was applied to hardware with the Apple Shuffle. Specifically, the Shuffle's lack of an LCD screen and the ability to select which song to play next were touted as a feature with the slogan "Life is random!"

I'd love to see other people's favorite examples of bugs marketed as features.
