Yes Joe Namath used to advertise panty hose on TV and my dad remembers watching those commercials when I was little.
He once told me that he remembered Joe Namath advertising panty hose and that is what made him famous and he said he used to laugh in a good way about it when it came on TV.
Joe Namath used to wear panty hose as well which is okay and nothing wrong with it but you could not get me to put on a pair of pantyhose no matter how much money you paid me.
But if Joe Namath or any other guy wants to wear or advertise Pantyhose they can do so and I don't have a problem with it.
