Love it or hate it, Valentine's Day isn't a Hallmark holiday. The day became popular during the High Middle Ages - between the years 1000 and 1300 - when 'courtly love'  was all the rage.

On the other hand, romantic movies are a creation of Hallmark, Hollywood and businessmen who have large money symbols as eyes (we joke). As Valentine's Day approaches, we thought we'd share some of our favorite love stories of all time.

Help us make this list grow, post your favorite romantic comedy below!

While You Were Sleeping (1995)

Before Sandra Bullock met Jesse James, she was working at the Chicago Transit Authority.

Well, sort of.

Bullock plays Lucy Moderatz, a CTA employee who saves handsome attorney Peter Callaghan from being run over by a train after he's knocked out cold. As the plot advances, Bullock's character somehow convinces Callaghan that she's his finance.

The 40-Year-Old Virgin (2005)

Some movies will stand the test of time no matter what and be remembered as a classic. This may be one of those movies.

Considered Steve Carrell's big break into Hollywood movies, this story is about, you guessed it, a 40-year-old virgin looking to score his first lay.

What makes this movie so memorable is the amazing supporting cast, including Paul Rudd, Romany Malco, Seth Rogen and Jane Lynch.

Breakfast at Tiffany's (1961)

When most people think of Audrey Hepburn, they probably imagine that iconic image of her posing on the cover of Breakfast at Tiffany's.

Winning Best Score in 1961, Hepburn plays a New York socialite who falls for her neighbor, who happens to be in love with another woman.

Knocked Up (2007)

How do you follow up with a movie like The 40-Year-Old Virgin? You make a movie about an accidental pregnancy involving polar opposites.

Seth Rogen somehow lands Katherine Heigl in this hilarious romp. Do the two change their ways for their baby in the end?
