In poll after poll, the most important factor for women when picking a guy is a sense of humor. If you look at the aesthetic imbalance between the leads in this weeks upcoming movies -- and -- it has to be true. While Mike Myers and Steve Carell arent bad looking guys, Jessica Alba and Anne Hathaway are grade-A knockouts. Check out some other memorable pretty girl/funny guy movie couples.

Seth Rogen is an immature pothead manchild. Katherine Heigl is a Nordic goddess with a hot career. One night of unprotected passion made them the oddest of odd couples. Its the movie that had millions of doughy nerds saying to themselves, "It could happen," with an equal number of women saying "Get real!"

John Cleese lives a life of quiet desperation until he encounters a stunning and scheming American jewel thief with a heart of gold (Jamie Lee Curtis). Cleese looks every bit the pale and put-upon middle-aged Englishman, while Curtis transforms herself from a horror flick scream queen to a crackerjack comedian in a skin-tight skirt. The result is pure comic gold.

Virginia Madsen is a radiantly fragile wine enthusiast, the perfect girl for Paul Giamatti, a shlubby failed novelist with a passion for pinot. When his best friends adolescent buffoonery gets too much for him to take, he transforms into someone worth falling for. Throw in some insanely beautiful California scenery and youve got an intoxicatingly good date movie.

This gorgeous gal is the object of obsession of pretty much everyone with XY chromosomes in the movie. Mary (Cameron Diaz) is pure, good-hearted and a complete knockout. And luckless loser Ted (Ben Stiller) wins her heart not through guile or money but by simply being a nice guy.

The Dude (Jeff Bridges) is the laziest man in Los Angeles County, which puts him in the running for laziest worldwide. He likes to bowl, drive around, have the occasional flashback, and is unconcerned about finding gainful employment. But he is apparently virile, which is enough for the heiress/performance artist Maude Lebowski (Julianne Moore).

Woody Allen is the granddaddy of the hot girl/average guy comedy -- and he looks it. In this film, he literally makes beautiful (if off-key) music with Julia Roberts and her nuclear-powered smile. Seriously, who writes this stuff? Oh, right. Woody does.

High school pastry aficionado Jason Biggs finds himself an improbably lucky man. The gorgeous scantily clad foreign exchange student (Elizabeth Shannon) in his bedroom is seriously into geeks. But what starts like every nerds fantasy turns into pure public failure.

Is this film an "average guy/gorgeous gal" flick or is it a rare "average guy/morbidly obese gal" movie? Whichever, it shows that any guy can truly see a womans inner beauty if hes hypnotized by Tony Robbins.

Pretty much every Adam Sandler movie fits in the hot girl/average guy mold. (Adam and Kate Beckinsale? Really??) In this one, even though his unhinged golf pro can't win a fistfight against a senior citizen, he does in the end manage to win the heart of brainy blonde Julie Bowen.

There are few movie couples more visually unequal than Joe Pesci and Marisa Tomei. Sure, Joe is short, hot-tempered and twenty-plus years older than Marisa, but he is a lawyer and a snazzy dresser. Of course, Marisa did end up with a short, bald guy named "Oscar."

A self-loathing, arrogant jerk (Bill Murray) transforms himself into a saint who can play a mean piano. Why? Because he longs for the affection of Andie MacDowell. Moral of the story: the average Joe can land a gorgeous gal though he might have to repeat the same day in an extremely cheerful small town over and over and over again.
