It's amazing how our minds work.
Even something that you can most assuredly say is stupid and ridiculous and absurd can be enjoyed beyond all reason if the memories associated with it are good ones.

It's a musical about train engines. All of the performers wear rollerskates. They sing about really weird shit and wear lights on their heads.
But watching it makes me feel happy because I remember a school trip to Europe: When we stopped in London, we saw this live. I remember giggling with my friends on either side of me. I remember craning my head around to see the actors zip by on the "tracks" that surrounded the stage, and realizing that everyone else had the same :D look on their face that I did.
So. Yes. Stupid as fuck. But good times, man. Good times.
