Continuity mistake: The buttons on Chris' and Peter's suits switch sides while they're at church. Also, when Lois goes to see Joyce after the news anchor's exposé, both women's buttons are a problem when the buttons do not change sides in the mirror's reflection. (00:04:00 - 00:13:30)
Continuity mistake: After Joyce reveals the secret on the news it soon cuts to Joyce sitting in front of the mirror at Quahog 5, and in the mirror's reflection we see the door behind Joyce opens at the real Lois' right side (blocking the lightswitch), but in the next shot facing Lois the door opens the opposite way (not blocking the lightswitch).

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.
