Has anyone listened to their favourite kid shows 15/20 years later and still know all the lyrics to the theme songs?

Like some shows I'd expect like, come outside, I love that show and Tweenies is one I loved. But I've been showing little one older shows - since every show out nowadays seems to have an agenda in mind. But I put on, big cook, little cook and bear in a blue house and those aren't ones I'd say I loved, but simply liked. Yet still knew every repeated lyric within the shows.

Don't you think it's strange the things your brain retains sometimes?
