Walking past the bakery section of a grocery store triggered an earworm for me two days ago. If you watched the sketch comedy show, "Exit 57," on Comedy Central, featuring Stephen Colbert as one of five performers, in 1995 or '96, you might remember it as the show's theme song. Eileen Barton had the biggest hit with it in 1950, but "Exit 57" used a different, arguably catchier version of "If I Knew You Were Comin,' I'd've Baked A Cake."
Good luck getting that melody out of your mind now.
