Some months ago, CK watched a movie on the flight back to Rome called Strange Magic. He's not the sort of person to be all for campy musical movies, but for some reason he loved it. We decided to watch it together, and I was initially iffy about it. But having watched the movie at least four times in the span of a couple months, you can say it's my go to feel-good movie. I don't know why, but it grew on me, and since then CK will break out into song, causing me to giggle profusely.
So yeah, this is entirely his fault. ;)
