Not my classroom:

In the class where we did English camp, I found steel cups behind the TV filled with rotting ramen and rice water...

I didn't look again, I ignored it, clearly wasn't my kids who did that as they weren't allowed to eat or drink in the classroom.

Also I have found used toilet paper on the floor of the classroom before, once again, not the English classroom - but WTF right?

Last year at my elementary school I found a 2,000,000KRW hand-held learning program thing for English.  Never opened.  I'm assuming they bought it because they had budget to blow, but c'mon.  It was something only one student could use at a time, and would have no practical application in class.  Pissing money away.

There were also some English materials I found that were developed by the Boseong country, before they started buying official textbooks.  One of the lesson plans was this monster game where the monsters had different names, heights, weights, backgrounds, hobbies, and countries of origin. 

There was one from Russia called the Vodka Monster, no joke.  The picture of it is him drunkenly pouring bottles of vodka into a funnel on his head, looking wasted, and its hobby is listed as "drinking vodka"

I think I also have something like that. A KMIT 크림북 (CreamBook). Looks like the attached picture, character case included. Just the one. Probably never used.

I've also found a Samsung TV Accessory Kit for my classroom monitor that includes three pairs of polarized 3D glasses. I've never remembered to download a 3D movie to see if I could get it to work.

At my old job, I found a book called "Randall the Red-Butt Reindeer". ^_^  Took a pic, but misplaced it.
