Earliest TV commercial you remember verbatim

For me it was every word of Whatever It Is I Think I See…

Boston area, around 1960. Some store, I think it was a furniture store, had the jingle:

How many cookies did Andrew eat? Andew ate eight thousand

for their telephone number, back when they used the letter-letter-number style for the first three digits so that number was AN8-8000. Every now and then it pops into my head and I have a nearly overwhelming urge to dial it, except I don’t know what the area code should be. 613 maybe?

Madge!
