That's it! The mystery is solved. While feeling ill tonight, I've had an incomplete jingle in my mind. At first, I thought it might be for Pepto-Bismol. Actually, however, it's for Alka-Seltzer. I've been thinking, "What's the jingle that goes, 'Something, something to the rescue?" Now, I remember. It's "Alka-Seltzer to the rescue," and that jingle is from the '80s.
I'm still taking Pepto-Bismol, however, because time is of the essence, and that's what I have.
