Remember when Chris Evans and Chris Pratt were in a rom-com together? Let's revisit.

Welcome to Chris-mas in July, a week-long celebration of our four favorite Hollywood Chrises. We'll be analyzing old movies, digging deep into past roles, and exploring everything there is to know about Evans, Hemsworth, Pine and Pratt. We hope this totally made up holiday makes you smile.

As straight white Chrises rise to power in Hollywood, it is the duty of the entertainment scholar to examine their history and the rare occasions where they may have crossed paths in the past.

Before Avengers: Infinity War, there were only two known instances of overlap between the Big Four Chrises: First, the Chris Hemsworth's cameo as Chris Pine's dad in 2009's Star Trek, and the fairly average 2011 rom-com What's Your Number? featuring Chris Evans and Chris Pratt.

And that, class, is the subject of today's lecture.

What's Your Number – based on 20 Times a Lady by Karyn Bosnak – is the story of Ally (Anna Faris), who goes back through her exes to see if she accidentally skipped over The One.

Evans stars as her playboy neighbor Colin, who begrudgingly helps with the search while repeatedly implying that they should sleep together.

Or as you may know it, the movie that brought us this:

Enter Chris Pratt as the ex Disgusting Donald, so named, apparently, because he used to be overweight – but perhaps more accurately because he now sports a weird thin mustache with a break in the middle. In the present, Donald totally has his shit together and is engaged to a beautiful woman. Ally keeps running into him despite having no interest, a running gag that only really works because the actors were married at the time.

There's even one scene where Colin mistakes Donald's house for someone else's and then he and Ally both trespass. A Chris-cross!

Beyond the Chrises, the movie is stacked with cameos including but not limited to Joel McHale, Martin Freeman, Andy Samberg, and fellow Avenger Anthony Mackie. Colin is meant to be a bit sleazy, but it's kind of fun to see Evans in that role after years as squeaky-clean Steve Rogers. He also leans into just a dash of a Boston accent and we can't complain.

Though fairly recent, What's Your Number? is a little too heteronormative, and slut-shamey to not notice. Ally's friends are horrified that she's slept with 19 people (this was two years after How I Met Your Mother had Barney sleep with his 200th partner), and the entire premise hinges on her sincerely believing that if she has sex with anyone else, she will lose her shot at romantic love.

Of course, the notion that sexually active women are somehow undesirable is part of an age-old binary foisted upon us by society. In one scene, Ally tells Colin that if her number gets too high, she's afraid she will no longer match some unknown man's ideal of the perfect woman.

Though it has its problems, What's Your Number? has charming leads and some cute moments, including a quintessential wedding climax for all the film's conflict.

It also makes us long for the days of Chrises in rom-coms. Hey Netflix, got any scripts lying around? We've got a role for not just one, but several leading men.

It's called Four Chris-mases. You're welcome.
