My parents are visiting me this month, and somehow we were randomly chatting about nursery rhymes. There was a particular one that we vaguely remembered but couldn’t recall the lyrics of – “Exercise is really great.” After struggling to remember it for a while, and then googling the name and failing to find anything, we remembered… my childhood audio cassette! When I was a kid, my parents would ask me to recite the songs and nursery rhymes I had learned and recorded them. Well, we did have an MP3 version of the cassette. Alas, my mom said we hadn’t actually recorded this particular song. A few minutes later, while I was annoying my wife with the MP3 of my childhood cassette, my mom jumped up out of her chair – the song was on it!
