The "Blowin' in the Wind" parody went something like this:

How many times must a man spray with Ban
Before he doesn't offend?
Yes, and how many times must he gargle each day
Before he can talk to a friend?
Yes, and how many tubes of shampoo must he buy
Before his dandruff will end?
The sponsors my friend, will sell you all they can.
The sponsors will sell you all they can.

How many times must a man use Gilette
Before shaving won't make him bleed?
Yes, and how many cartons of Kents must he smoke
Before the girls all pay him heed?
Yes and how many products must one person buy
Before he'll have all that he'll need?
The sponsors my friend, will sell you all they can.
The sponsors will sell you all they can.

How many times must a gal clean her sink
Before Ajax scours out that stain?
Yes and how many times must she rub in Ben-Gay
Before she can rub out the pain?
Yes and how many ads on TV must we watch
Before we are driven insane?
The sponsors my friend, will broadcast all they can.
The sponsors will broadcast all they can.
