So what kind of animal would you suggest for someone who just wants a natural lawn mower? 
(Back when my dad and I still had our house, there were some questions or requests he would resist unless I found the right way to ask. So it got to the point where "It's time to ask Nick about renting a goat" was code for "would you please mow the <censored!> lawn?!". Since Nick was my dad's friend and owns one of the Greek restaurants in town, and they serve goat there, this appealed to my dad's sense of humor. Yeah, it's weird, but it got the lawn mowed.)
