Morris walks into Dr. Cohen's office and puts a note on the table in front of the doctor. The note reads, "I can't talk. Please help me!"

The doctor thinks for a while and says to Morris, "Put your penis on the table here."

Morris thinks this is a bit weird, but Cohen is a specialist, so he does as the doctor says.

The doctor takes a rubber mallet and hits Morris's penis as hard as he can.

The man cries in great agony, "AAAAAAAAAAAAAAAA!"

The doctor says, "Good. Come again tomorrow, and we'll learn B!"
