For Cellar door, I first heard it in the 2001 movie Donnie Darko.

Donnie Darko (Jake Gyllenhaal) is speaking with his teacher Karen Pomeroy (Drew Barrymore). He sees the words ?Cellar Door? written on the chalkboard and asks her what it means and she says:

?This famous linguist once said that of all the phrases in the English language, of all the endless combinations of words in all of history, that Cellar Door is the most beautiful.?

The famous linguist she is referring to, I understand, is J. R. R. Tolkien from his 1955 essay "English and Welsh".

I like Cellar Door because the movie Donnie Darko resonates with me.
