I heard this on the radio ONCE, in Oklahoma in the mid 50's. I can't see it but it must be truly awful for me to have remembered it all these years. A Peggy Lee clone sang:

We're havin a heat wave
A tropical heat wave
For coolness and slumber
Just dial our number
Armor 04-04
It's Exoteric

It must be horrible but I don't understand why. PS. Phone numbers were shorter then.
