service manager to come and take a look at his bike when the
mechanic shouted across the Garage, 'Hey Doc, want to
take a look at this?'

motorcycle. The mechanic straightened up, wiped his hands on
a rag and asked, 'So Doc , look at this engine. I open its heart,
take the valves out, repair any damage, and then put them back
in, and when I finish, it works just like new.


So how come I make $39,675 a year and you get the really big
