My Best Friend's Girl is a 2008 American romantic comedy film directed by Howard Deutch, written by Jordan Cahan, and starring Dane Cook, Kate Hudson, Jason Biggs, Diora Baird, Alec Baldwin, Riki Lindhome and Lizzy Caplan.

Throughout the evening, Tank behaves like a rude, vulgar Neanderthal, causing the woman he's out with to realize her ex is not really so bad after all and go back to him.

Initially turning him down, the next day, he sees Alexis flirting with another co-worker and begs Tank to take her out and he accepts.

Dustin sends Alexis roses and an apology poem in Tank's name, and she calls him, berating him for leaving early the previous night.

Tank goes to see her, and they end up having casual sex on a regular basis while Dustin begins various desperate attempts to stay friends with her.

Becoming even more upset and refusing to leave, he starts to walk up the stairs only to discover that the man Alexis has been sleeping with is Tank.

After overhearing Alexis telling Rachel she has fallen for him, Tank's guilt causes him to sabotage their relationship and apologize to Dustin.
