How to grow an Avocado Tree

Jessie Cross of The Hungry Moose blog describes the process in detail, but basically, you:

1. Eat an avocado (fun part)
2. Clean-off the pit
3. Suspend it over a dish of water with toothpicks (half-submerged)
4. Wait 3 to 6 weeks for it to sprout

Simple enough, right? Now, I can't guarantee that you'll have fruit for even a year or two, but it's worth the wait.
