RE: Warmed Dr. Pepper
Yes, the ads had hot DP in a glass coffee cup and saucer, with the slice of lemon afloat. I had a black & white 16mm copy of it in my high school (Skyline) cinematography class in Dallas, home to DP. BTW, there is still a plant (the oldest one) in Dublin, TX, that uses only cane sugar in their DP. I buy cases of the stuff here in LA.
Remember how DP suggested you drink it at 10, 2, and 4?
