Does Advertising Work?

I wish that I could take credit for this little poem but I can't. I found it on the website of another marketer, Rick Tracewell (www.ricktracewell).  He says that it is a famous poem but I can't seem to find the author of it. In any case, it makes sense.

Why Is It?

A man wakes in the morning after
sleeping on an ADVERTISED mattress,
under ADVERTISED sheets,
and in ADVERTISED pajamas.
He washes his hair with an ADVERTISED shampoo,
cleans with an ADVERTISED soap,
shaves with an ADVERTISED razor,
using ADVERTISED shaving cream,
and puts on ADVERTISED deodorant.
He pulls on ADVERTISED blue jeans,
an ADVERTISED shirt and ADVERTISED sneakers.
He'll drink ADVERTISED coffee after
his ADVERTISED orange juice, cereal and
toast (from his ADVERTISED toaster).
He will drive to work in an ADVERTISED car,
sit at an ADVERTISED computer,
in an ADVERTISED office chair,
and write with an ADVERTISED pen.
Yet this man hesitates to ADVERTISE,
saying that advertising
does not PAY.
Finally, when his UNADVERTISED business goes under,
he then ADVERTISES that it is FOR SALE.
