Small Engines (Lawn Mowers, etc.): humans/animals, flathead screwdriver, eyes and ears

Question
Can you describe the similarities between humans and animals? Also, how do I repair my lawnmower with nothing but a cat tooth and flathead screwdriver?

Answer
Why yes I can.  We both have a mouth and eyes and ears and feet and hands a head oh and don't forget hair.  Golly we are just alike.  I think the only difference is opposable thumbs.  I have never used a cat tooth before, but now that I think about it what a great idea. As a matter of fact a great use would be using the cat tooth to dig grime out of crevices in the lawn mower you can't reach.  You have to market that idea.  You will be a rich woman.  I wish I thought things through enough to come up with ideas like that.  You have to be a genius in some respect.  I mean cat tooth and lawn mower how would one even know to use a cat tooth for something like that.  I wonder where you would market that idea.  petsmart or home depot?  You got me, but then again I am just a small engine repair EXPERT.  I don't have the genius behind using a cat tooth for lawn mower repair.  Great idea!!
