This is a rerun. I linked to this commercial some time ago but the video was deleted from the website that hosted it. Here it is on another one. Nothing says "sixties" like this kind of ad.
It's one of my favorite commercials for one of my favorite products of the period — Adams Sour Gums. I was never much for chewing gum but I liked their Sour Orange and occasionally their Sour Lemon, and would pick up a pack now and then until they stopped making all four flavors. Recently, the company that now owns Adams brought back the two flavors I never liked — Sour Apple and Sour Cherry — in a limited release. Naturally, this prompted me to call up and demand they reissue the Sour Orange or at least the Sour Lemon. A nice lady on the phone said they'd look into it. That was a year ago and I'm still waiting, Nice Lady on the Phone.
Here's the commercial. That seems to be actor Barry Newman, who later starred in a fine lawyer series called Petrocelli, doing one of those jobs that actors do before they get a series.
