Bad timing allowed “What’s Your Number?,” a mildly raunchy romantic comedy about a woman lamenting her sexual history as she resolves to finally save herself for Mr. Right, to come out mere months after the too similar “Bridesmaids.”

And bad timing is evident on the screen, as well, as this comedy struggles to find a tone, find its footing, find any comic momentum that two generally funny leads could carry across the comic finish line. Anna Faris and Chris Evans don’t have enough scenes together, don’t have enough funny lines and aren’t surrounded by enough funny people to give this “Bridesmaids-lite” a shot.

Faris plays 30something Ally, who uses the day she is laid off from her marketing job to read an article detailing research that shows that women who have had more than 20 sexual partners are less likely to marry. Ally tallies herself up, figures she’s at “19,” and promptly gets drunk, sleeps with her creep boss, and now must track down her previous 19 so that she can rekindle an old flame and not cross that Marie Claire mag-decreed number of doom.

Her assistant in this search (Yes, she starts on Facebook) is her randy player of a neighbor, Colin, played with shirtless (and often pantless) charm by Chris Evans. He’s been ducking into Ally’s apartment in order to not have breakfast with each night’s conquests.

“You’re a peach,” he tells her, for letting him avoid “hurt feelings” amongst his bevy of babes.

“You’re a pig,” Ally snarls back.

A cute running gag — Ally keeps meeting her exes, and each is odd in his own odd way. And she was odd around them in an effort to court them. She dated a Brit, and faked a British accent to seal the deal. Does she still remember her “My Fair Lady” lines, guvner?

Ally is also helping her younger sister, Daisy (Ari Graynor) prep for her wedding, giving Faris a chance to show off her “drunk” engagement toast shtick. She stuffs her face with samples of the wedding cake Daisy might choose.

“Nobody’s ever going to see me naked again” is her excuse.

It’s no longer a shock to hear the buxom blonde next door swear like a frat boy as she talks of her frat-boy friendly sex life. And it doesn’t help that we meet Faris in a scene identical to the opening moments of “Bridesmaids” — slipping out of bed, freshening up so that she can pretend to be that pretty even when she wakes up.

The banter with Evans is often first-rate. “If these girls can’t see you coming, they deserve what they get!” There’s just not enough of it. They have a few cute set-piece scenes, just not that many.

It’s a movie that lacks urgency, despite Ally’s protests that “I’m running out of time, money and viable eggs” during her man hunt. The director, “Entourage” vet Mark Mylod, doesn’t have either a light touch or a pound-out-the-laughs feel for the material, so lines are lost, situations fail to deliver and Faris and Evans never quite click the way the script ordains them to.

Thus, “What’s Your Number?” fails to add up to anything we haven’t seen before, and recently and now on video.
