Years ago, my senior year of high school to be exact, my friends used to recite this commercial, over and over, to each other. Somehow I'd missed seeing the commercial itself, but I became very familiar with the bit. And I shared the joke with my family, and we repeated it so often on our trip to California and back that it was banned in the house for a while. But we can laugh about it again now. It goes something like this:
Me: I don't believe you.
You: Well, who would you believe?
Me: Oh, I don't know... maybe... Robert Loggia!
All together: Whoa, Robert Loggia!
I've searched for the commercial a few times but to no avail. But thanks to the miracle of YouTube, I can finally share the commercial with you. Enjoy!
