Just noticed something about a song in a beloved Christmas special.
In Snow Miser's song from The Year Without A Santa Claus, during the verse about preferred temperatures, he abruptly switches from farenheit to celcius. "I never want to know a day that's over 40 degrees. I'd rather have it 30, then 20. 10. 5. then let it freeze" The first sentence is presumably in farenheit becuase 40 degrees celcius would be very hot even for summer. But the second part is in celcius because in farenheit temperatures water freezes at 32 degrees, not zero.
