For the ballot to choose the AFI 2002 Top Love Stories, I submitted the following:

Crossing Delancey (1988)
Gone With The Wind (1939)
Grease (1978)
The King And I (1956)
Love Affair (1939)
Moonstruck (1987)
Murphy's Romance (1985)
My Fair Lady (1964)
The Philadelphia Story (1940)
Say Anything… (1989)

They may not be the best, but they're my favorites, and I've seen each and every one of them at least twice, if not 5 or 6 times.
