I live in Burbank, and frequent the original Big Boy...love that Special :)

I still have a gold-colored birthday token somewhere that I got from being in the birthday club when I was just a youngster and we used to frequent the Big Boy in Spokane Washington....

They used to send them out each year at your birthday and you could take it in and trade it for a burger or something along those lines.

I keep telling my wife I should take it into the Original Big Boy in Burbank (may actually be Toluca Lake) and slap it down on the counter and ask for my Birthday Burger .... *LOL*
