The teacher says to her new class, "For our first lesson, each of you will stand up, tell us your name, say what your father does, spell what your father does, and then explain it to us. All right, Billy. You go first."
Billy stands up and says, "My name's Billy. My father's a lawyer, l-a-w-y-e-r, and he defends people in court."
The teacher says, "Very good. All right, Benjamin."
Benjamin stands up and says, "My name's Benjamin. My father's a pharmacist, f-a-m... f-a-r-n... f-n...."
The teacher says, "Benjamin, you go home tonight and learn how to spell pharmacist. Angelo, you're next."
Angelo stands up and says, "My name's Angelo. My old man's a bookie, b-o-o-k-i-e, and if he was here, he'd give you even-money odds Benjamin ain't spellin' pharmacist by tomorrow."
