Stride Stripe Gum

This ad is a year old, but I think it's already considered a classic. The idea here is that the flavor lasts a very long time, like since we were monkeys. Even now, when we've evolved to be 17 year-old models, the flavor is still going strong. At the end she thinks, "Huh, how long have I been chewing this gum?" It's hard to say if this gum is also a time machine that simultaneously  causes one to evolve, or if she is some god that can evolve on her own during millions of years. Either way, this gum is magic.
