Tuesday night's cupid - episode 3

Last night's episode of Cupid is titled The Great Right Hope.
When Marshall, product of a sperm donation, hacks into the donor bank to find out about his dad, he learns about and then meets up with Clint, a boxing instructor, who he begins to take lessons from (without telling him who he is). He decides to set up his mom with Clint, in the hopes that they will hit it off together. Unfortunately, just about everything Clint is and stands for -- his political beliefs, his profession, etc., is at direct odds with her pacifist, leftist ideals. In the meanwhile, Claire has an unpleasant and unexpected house guest in her rather ditzy mother.
