Pease porridge hot

I like the Japanese translation of "Some Like It Hot", "Oatsuinoga Osuki". Japanase titles of old foreign movies are nice. Titles these days are not so interesting. Just English to Katakana.

I've been wondering like what's the meaning of "Some Like It Hot"? Now I found that this title was from a nursery rhyme, "Pease porridge hot".

Pease porridge hot,
Pease porridge cold,
Pease porridge in the pot
Nine days old.

Some like it hot,
Some like it cold,
Some like it in the pot
Nine days old.
