Plot hole: They're in the Clam complaining that they can't drink when they make the revelation that Brian can because he's technically 56. But Quagmire should be able to drink, as in a much earlier episode, he's revealed to be over 60.

Barely Legal - S5-E8
Connie: You know, Meg, there's no dogs allowed. So, you're going to have to leave. But Brian can stay.
Brian Griffin: You know, Connie, I think I have this theory about why you're such a bitch.
Connie: Excuse me?
Meg Griffin: Brian, let's just go.
Brian Griffin: No, no, no, no, no, no. Hang on a minute, Meg, hang on. You see, Connie, you're popular because you developed early and started giving handjobs when you were twelve. But now you can't stand to look in the mirror because all you see is a whore. So you pick on Meg to avoid the inevitable realization that once your body's used up by age nineteen, you're gonna be a worn out chalky skinned burlap sack that even your own stepdad won't want. How is that? Am I in the ballpark?
[Connie runs off crying].

No Country Club for Old Men - S11-E22
Question: Stewie says "Megs Benedict" after Carter pukes all over her. Why is it funny?
Suggested correction: Quagmire considers the rest of them to be his best friends. He isn't drinking because they can't drink. He is complaining because since his friends can't drink - he won't drink, so he is still pissed.
It's still a plot hole considering Quagmire's age. I think the writers messed up big time.
You make a good point, but it's awkward to be that one person who is drinking while surrounded by people who can't. So, I understand the correction that was submitted above. Because his friends are not drinking, he now feels that he can't.
It's 100% a mistake. Quagmire simply would buy them alcohol the same way Brian did when they realized he could.
