A customer at Green's grocery thought that the owner was very smart and asked,"Tell me,what makes you to smart?"
"I wouldn't share my secret with just anyone,"Green said,lowering his voice so that the other customers wouldn't hear him,"butsince you're such a good customer,I'll let you know it.It's fish heads.Eat enough of fish heads and you'll be smart."
"Really?"said the customer."Do you sell them here?"
"Sure.Only $4 each,"Green said.The customer bought three,but came a week later complaining that the fish heads were bad and he wasn't any smart.
"You didn't eat enough,"Green answered,so the customer bought 20 more.Two weeks later he went into the Green's shop angrily once again.
"Hey,Green,you're fooling me.You sell me fish heads for $4each when I can buy a whole fish for $2."
"See!"Green said."You're smart already!"
