I love a great slogan, and I love Old Spice. Their slogan is "If your grandfather hadn't worn it, you wouldn't exist!" However, if you note the top line on the box, it says they have existed since 1938. I was born in 1937, so I guess my granddad must have used rye whisky or something else.
My Dad used Old Spice, and I love the smell. ;-) He must have purchased his first bottle after I was born. ;-)
