Ideaphiles rejoice at the Half Bakery

I love reading Scott Adams' blog. About every 5-10 posts he has one that is a totally creative and somewhat crazy idea or way of thinking about the world, which actually makes a ton of sense. And he recently referenced the Half Bakery, which looks like it's been up for many years now giving people a place to post just such half-baked ideas.

Some of my favorites:

1. Custard-Filled Speed Bumps (of course by "custard" he means a dilatant substance, such as a corn starch and water slurry)
   
2. Ball Dogs - Next time Wimbledon is about to be held, organise 4 or 5 of the sort of dogs who are insanely obsessed with retrieving balls to fill in for the ball boys/girls.
3. 30 cat night - a more granular scale than the famous 3 dog night.
