Git 'er Dun (or fess up)

If you tell someone you're going to do something by a given date, I feel you should be required to do one of the following:

• Get the 'something' done on time
• Have the huevos to fess up to not getting your shit done

There's nothing that I hate worse (well, maybe some things, like cats, or Indiana) than people that say they're going to get something done and then conveniently "forget" to mention why it's not done.

There should be come kind of a common social penalty for this. I'm not sure what, but it should be creative. Maybe you should be forced to drive to work on a moped for a week (those of you who don't live in the Midwest won't appreciate this), or possibly be made to stand in front of a stone wall and have to dodge fast-moving projectile rodents??? I don't know, but I'm sure I could think of something.

Anyone have any ideas?
