Why I remember random line from a movie which I watched 10 year ago

When I was a kid there was a song that I guess was popular around here that mocked bald people with several "pet names", one of them was "Moskito Airport".

Over a decade later I started taking the train to go to work and it took me literal years to stop getting that song pop up in my head every time the train announced the airport station. Nobody around me even remembers that song exists. I don't even remember who sang it or where it would play, but still - listen to the word airport and the song starts playing in my head. Same thing is true for pretty much every word that is not often found in song lyrics.
