I don't think this one's been up yet.
Oh you need fluff, fluff, fluff to make a fluffer nutter,
Marshmallow fluff and lots of peanut butter.
First you spread, spread, spread your bread
with peanut butter,
Add marshmallow fluff and have a fluffernutter.
When you enjoy, joy, joy your fluff
and peanut butter,
You're glad you have enough for another
Someone hit one of the verses of the Narragansett Beer "jingle" (it was closer to a dirge) from the 70s, but I think the main verse was:
I can see the sunlight shining
Over Narragansett Bay
So fill a glass my friend
And talk to me of home, of home.
That replaced their old slogan "Hi Neighbor! Have a "Gansett!"
Most surprisingly offensive I can recall was a radio jingle for a Japanese tuna brand.
Three Diamonds brand, fancy tuna
Fresh as the ocean breeze
It's good for your diet
Clear and mild
And low, low, low in calories
