I really liked this -- drew comparisons to Seinfeld stuff -- the "Man Hands" episode and the episode where Jerry's date interest looks attractive only w/ the right lighting. Also, "Shallow Hal" with Jason Alexander's character focusing on his ridiculously hot girlfriend's weird toe.
Now, at first I thought this was a bit superficial -- your male lead is very superficial. But it felt a little misogynistic. Though, when everything came around with your lead, I was satisfied. He got what he deserved and was (SPOILER ALERT) dumped for the same exact reason he was thinking about dumping his girlfriend.
I do think the dialogue could've been more creative and naturalistic, specifically at the beginning between the two dudes. As is, the dialogue is just pretty much only there to push narrative. I think you can get some better laughs with some solid one-liners/jokes en route to the punchline.
