I'm no Quack: A Book of Doctor Cartoo by Danny Shanahan
Shanahan will have you in stitches (metaphorically, of course), from a nutcracker performing a prostate exam, who says to his patient 'Turn your head and scream,' to an 'Outingpatient' room in which the receptionist calls out 'Closeted gay Mr. Sherman? The doctor will see you now,' to a practitioner who comforts a frightened spouse 'You can rest assured, Mrs. Wilson, that your husband will receive the best care known to medical coverage.'
