Two guys go hunting.  Jerry has never gone hunting while Joe has
hunted all his life.

When they get to the northern Wisconsin woods, Joe tells Jerry to
sit by a tree and not make a sound while Joe checks out a deer stand. 
After he gets about a quarter of a mile away, Joe hears a
blood-curdling scream.

He rushes back to Jerry and yells, "I thought I told you to be
quiet!"

Jerry says, "Hey, I tried. I really did.  When those snakes crawled
over me, I didn't make a sound.  When that bear was breathing down
my neck, I didn't make a peep. But when those two chipmunks crawled
up my pants leg and said, 'Should we take them with us or eat them
here?' I couldn't keep quiet any more!"
