These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Paul Simon
Ear Worm: many. "Mother and Child Reunion," "Kodachrome," "Me and Julio Down By the Schoolyard," "50 Ways to Leave Your Lover," and "You Can Call Me Al" are good examples.
Hilarious in Hindsight: The chorus of "Kodachrome" is "Don't take my Kodachrome away!". As of 2009, that's exactly what happened, with the discontinuation of Kodachrome slide film.
