I had a great idea of getting a goat to mow my lawn for me. I figured in the winter when the grass didn't grow we could just eat the goat, and get a new one in the spring!
Coincidently, on the exact same day the Straightdope posted about the same topic!
It had to be ewe: Could sheep replace the lawn mower?
Apparently the upkeep of goat/sheep would be more work then just actually mowing the lawn. I am so dissapointed...
