I've been giggling hysterically at a story called
Fourteen Experiments in Postal Delivery.
You can find PodCastle's reading of it
here. I highly recommend it, not just for the story. The style in which it is written means it is very suitable to being read out loud and/or listened to.
For those of you who prefer reading, you can find the full text of
Fourteen Experiments in Postal Delivery here.
Go have fun.
If you're done, feel free to poke around
here, which is lots of fun as well.
