While hanging out together at a bar, Jay and his friends run into Cameron, whom Jay introduces as "a friend of my son's", carefully avoiding Cameron's relationship with Mitchell. This annoys Mitchell, and decides to talk to his father about it. Jay tells him he was just trying to avoid an awkward situation with a bunch of people with old attitudes. Mitchell then tells him that he believes that Shorty, one of his friends, is gay. Jay vehemently denies it, but when he informs Gloria of Mitchell's opinion, she agrees with Mitchell, since Shorty has never tried to flirt with her. She insists Jay to talk to his friend about it, so he decides to invite Shorty to go play golf. Jay begins noticing some signs after he starts watching how Shorty acts. He starts to think that it may be possible. Jay settles for coffee and finally tries to get Shorty to open up. Jay admits he didn't handle the situation well with his son, and offers himself to support Shorty and doing all he can to help him. Shorty then tells him however, that rather than being gay, he owes a bookie $20,000. He assumes that Jay is willing to lend him the money, and considers it beautiful. Jay confronts Mitchell, telling him that in offering his support to Shorty instead he had to loan him $20,000 to cover gambling debts. It turns out that Mitchell never believed that Shorty is gay, he was just teaching Jay a lesson for introducing Cameron as "a friend of my son's". But Mitchell tells his father he's proud of him, for becoming more open-minded than he was when Mitchell was younger.
Manny is preparing himself for his blind date with a girl named Whitney, whom he met in an online book club. Unfortunately, when she arrives, Gloria and Manny discover that Whitney is actually an adult woman, who didn't know that Manny is a child because he seemed so mature online. Whitney feels so ashamed and stupid, and believes that she'll be alone for the rest of her life. Gloria and Manny try to comfort her, and Gloria ends up giving her a makeover so that she can feel better about herself. Later, Cameron comes over to bring Gloria some flowers for babysitting Lily. He immediately shares a strong connection with Whitney, and she thinks he might be "the one".
In the meantime, Cameron is freaking out over the appearance of limp flowers he has bought for Gloria. Mitchell is surprised for this, as Cameron is completely bothered by the flowers, but when Jay introduced him as "a friend of my son's", he didn't bother about it. But Cameron points that this is because Jay didn't mean any harm and the florist played him for a fool. The florist comes over to replace the flowers, but when the old ones suddenly start looking better, Cameron microwaves them to make them look bad again. However, as a result of the microwave, they start to burn, and Cameron freaks out in front of Mitchell and the florist.
Meanwhile, Phil has just installed a home theater system in their living room. However, Claire doesn't understand electronics, so she has some problems using the master remote control for the home theater system.

He buys another remote control and has to teach their "dumbest kid" how to operate it in 20 minutes or less. Although Phil first wants to teach Luke, Claire demands him to teach Haley, as she doesn't understand electronics either. Haley has initially no interest in learning how to work the remote, but Phil convinces his daughter to learn the ways of the home theater system because they would both love to prove Claire wrong. She finally learns to use it successfully, making Claire feel stupid for not knowing how to work it. Once Phil is asleep, Claire begs Haley to teach her, and she finally learns it.
