oh_oh_sheila posts a very short entry to the guinea_pigs community:

"Do you think guinea pigs get high if they're around pot smoke? I think so. Mine is a lot more chill after someone smokes in the room. She's usually hyperactive and whistles a lot."

All. Hell. Breaks loose.
Lots of "OMG UR SO CRUEL" and "We should sic PETA on you!" and the like, plus a long debate that leeches over onto stupidpetowners on the topic of whether it's okay to 'accidentally' get your pets stoned.

The stupidpetowners post is friends locked, the guinea_pigs one wasn't, then was, and last I checked was unlocked again.

ETA: The mod has brought out the Stick of Deletion.
In case said mod also deletes their own post, here's what we have:

"Mod note:
I deleted the weed post because I consider it trolling. It was deliberately inflammatory as the poster did not seem at all interested in the advice she was getting for the health of her pig. It also was somewhat inappropriate for community, given that the community is open to members of all ages. No, I'm not the DEA or Nancy Reagan, but there is absolutely no need for that in this community. In case anyone has a GENUINE question about this, let me just state for the record that it is most likely a bad idea to smoke up (or smoke anything) around your pig. I really don't care if you all agree or disagree with that, but that's is all that is going to be said on the subject in this community because I don't want people discussing drugs in this community. As far as this community is concerned, do whatever you want with your body, but don't impose it on your pet, child, or anyone else who has no power to protect themselves.
I really hope this conversation is finished because frankly it's absolutely ridiculous. While the original poster bears the brunt of the responsibility for this, the 173 comments, many of which were no more coherent than name-caling were ridiculous as well. Let's not dignify trolling by stooping to the level of trolls."

oh_oh_sheila finds herself banned from the guinea_pigs community, and laughs about it in her own journal.
