Help! I've fallen and I can't get up!

Back when that commercial was playing I had my answering machine respond with:

(old lady) I’ve fallen, and I can’t reach the phone!
(young man) Please leave your number and we’ll call you when Lifecall arrives.

Hey, it was funny the first couple of times.

I remember a song that was sung on the schoolbus after this commercial came out…

“Help, I’ve fallen and I can’t get up!
Stuck to the floor like a peanut butter cup!”

It came from a Wendy’s commercial. It was big in the 1980s. The Simpsons referenced it in a double-reference, I recall. The newspaper from the day Lisa was born featured an actual event- Walter Mondale using the “where’s the beef?” line to comment on the lack of “beef” in his opponent’s promises. Lisa was confused. Homer was in hysterics.
