Aah remember one where they wrote a 'hospital story' to the tunes of 'Oklahoma'

Chorus (after the patient snuffs it)
Oh what a bad operation
Watch how the law suits roll in (or something like that

I loved MAD magazine (and still do in small doses) but I think I just got tired after about eight years
