In my research for old Coke slogans, I found some of the earlier ones downright hilarious.

“For headache and exhaustion, drink Coca-Cola”
“Ice-cold Coca-Cola is everywhere else – it ought to be in your family refrigerator”

and my personal fav:

“The favorite drink for ladies when thirsty, weary, and despondent”

EDIT: The punchline in this one was a gift from one of the last PWITM entrants: catfriedrice!

Much thanks for letting me “borrow” a great line!
