This is a short from the comedy website Funny or Die and as such cannot be expected to take a concept too far. However, in this case, I believe they took a funny concept and didn't take it as far as they could have.
The film follows Judy, who is very good at meeting the needs of her best friend, but doesn't have much of a life on her own. There are references to several rom-com tropes, which are funny enough. Judy finally meets a guy who might be interested in her, but she quickly sets him up with another friend of hers.
At this point, this short had me laughing enough that I was intrigued to see this film carried on a little bit longer. While there certainly is the risk of repeating the same joke over and over, I think this could have been stretched out to seven or eight minutes and still been as funny.
Overall, this takes a funny idea and delivers, but ends a bit too abruptly.
