I once heard an excellent spoof of this song, I don't know who did it but it was something like......

I'm an Adman, I know what I'm saying,

you're hair's getting grey and your teeth are decayin'

you're getting old & decrepit, etc. etc.

And you tell me over & over & over again my freind,

that you don't believe, you're on the eve of destruction.

If I recall correctly, the guy had a lot of products to sell.

Frank.
