But would you believe, in an episode called "Beer Bad," that the beer was bad? Would that blow your tiny little mind? Anyway, it is. It's very bad. Drinking it turns these jerkbag college kids into cavemen.

Buffy, who's illegally drinking as well, suffers the same effects, and ends up painting stick figures in her room.
With what we're sincerely hoping is not slayer feces.
It turns out that the beer was spiked with a magic potion, because the owner of the bar was gently bullied by college kids over the years. He flat-out admits all this to Xander after seconds of interrogation. And how did he pull off this incredible transformational poisoning?
Look, it was a good show in general.
Hilariously, this episode only exists because Buffy was trying to take advantage of a government subsidy to incorporate anti-drug storylines into popular shows. Despite crafting this whole stupid plot with that goal in mind, the episode was rejected by the program for its "otherworldly nonsense." It didn't show the real dangers of substance abuse, the government argued; it showed the dangers of vindictive tavern managers with warlock relatives. A situation the government is apparently neutral on.
