What's Your Number? follows Anna Faris' Ally Darling as she impulsively decides to make a list of all the men she's slept with and is horrified to discover that her number is much higher than any of her friends, with the film subsequently detailing Ally's efforts at tracking down the aforementioned men to see if perhaps she judged them too harshly. (There's also an ongoing subplot revolving around the friendship between Ally and Chris Evans' hunky neighbor, as his character assists Ally in locating the folks on her list.) For the most part, What's Your Number? plays like a bottom-of-the-barrel sitcom that has absolutely no basis in reality, as scripters Gabrielle Allan and Jennifer Crittenden augment the unreasonably over-the-top premise with a series of unfunny jokes and comedic set-pieces.
