Last weekend during a birthday lunch treat, my sister jokingly mentioned the tv commercial of yore which says - Sarsi with egg. Sarsi is a brand of root beer and the muscleman in the commercial mixes 2 egg yolks in a glass of that root beer. Drinking it would give you not the muscles but the energy of a muscle man like him. I don't know if it is true but I remember that Sarsi was one of the leading brand of soft drinks at the time.
