Scarlett Johansson is returning to host "Saturday Night Live" for the sixth time this weekend. Doing so will give her an opportunity to work with her fiancé, "SNL" co-head writer Colin Jost.

Humor is clearly something that unites the pair. And Johansson isn't alone. There have been so many romantic couplings between Hollywood bombshells and the funny men of "SNL," it's beginning to look more like a matchmaking service than a late-night show.

Oscar winner Emma Stone got engaged this month to "SNL" writer and segment director Dave McCary, whom she met in December 2016 when she hosted. In May 2018, romance sparked between "SNL" actor Pete Davidson and singer Ariana Grande and while that relationship fizzled out, he went on to woo many other beautiful, famous women, such as actress Kate Beckinsale, in spite of the fact that, by his own admission, "I look like I make vape juice in a bathtub."

Yes, funny men have always been able to attract amazing women (see: Woody Allen and Diane Keaton; Mel Brooks and Anne Bancroft).

But those funny guys were richer, more famous and more powerful than the women they attracted. The "SNL" guys have all wooed women who are considerably richer, more famous and more powerful than them. According to the website Celebrity Net Worth, Johansson's wealth is estimated to be $165 million, while Jost's is around $6 million.

Last summer, Charlize Theron exemplified this trend when she played a gorgeous, fiercely competent secretary of state who falls for a nebbish, but extremely funny reporter played by Seth Rogen. The movie's title is "Long Shot" — and yet beautiful, successful women falling for funny ordinary guys isn't that unlikely any more.

According to Fortune, women in their early 20s are now out-earning men. We don't need to search for a man who can provide financial stability the way we used to. After a long day at the office, nothing sounds less appealing than having to cater to a serious Don Draper type at home. Lots of women would rather have someone who can make them laugh about their job, and take their mind off their own work.

In a 2007 study of 200,000 people, published in Archives of Sexual Behavior, women ranked humor as the first of their preferred qualities in a mate. Another 2009 study presented at the British Psychological Society Annual Conference found that women were inclined to rate candidates with the funniest profiles as more likely candidates for long-term relationships.

The World Economic Forum noted that, "Evolutionary psychologists describe humor as a heritable trait that signals mental fitness and intellectual agility to prospective mates."

And while funny guys are usually smart, smart guys aren't always funny. (See: Mark Zuckerberg.) If you're faced with a choice between a stoic genius, and a man who can make you belly laugh every day — for life satisfaction, who wouldn't go with the latter?

Others seem to feel the same. As yet another Hollywood beauty Olivia Wilde told iVillage, of her fiancé, former "SNL" star Jason Sudeikis, "He keeps me laughing … Funny guys are always the best, and I think it works on all us girls."

Because god, humor helps in a relationship, especially in the modern world.

Take it from me. I've been married to a "Late Show" writer who has kept me laughing for five years. His humor was the thing that broke down my single girl defenses — when we first met and I tried to tell him I wasn't looking for anything serious he laughed and replied, "we'll just get married for two years then."

We got married two years later. The continuing laughter he's brought into my life has given me more joy than any Wall Street bonus ever would.
