well, there is that whole “cow-orker” thing… 
Yah, I know; I guess if I hadn’t put that in there, I wouldn’t have had a single response. Still you did say “the OP’s point”; and I did say I was flattering myself. 
This is why, when I worked at a large medical clinic that had an in-house lab, absolutely no food or drink was allowed in the lab. You couldn’t even walk through it with a Diet Coke in your hand. When the techs took breaks, they had to stay in the break room. They were super-strict about it.
This is pure, unadulterated genius. And some pee.
In our Bio research lab at my university, we usually recieved the dead mice and rats from the Psych department. We used them for dissection purposes, but they were stored in the freezer… I used to put my frozen lunch in there on many occasions… You should have seen the looks I got when I pulled my lunch from a freezer containing dead animals…
Almost as gross as cooking soup in the autoclave (it tastes ok)…
Ummm…If put a biological sample of any kind, no matter how relatively safe, in the “food fridge” I would, as fast as you can say “terminated”, lose my effing job. Faster, even. And, if I put food in a fridge where biological samples are stored, I would, again, lose my effing job.
To put it bluntly, unless your lab has no safety standards whatsoever, you will never find out who did it. If, however, there are some minimal standards, and the guilty party fesses up, it may be necessary to fire his or her ass for being, above all else, the world’s biggest idiot for admitting they did it.
I know that the culprit will never come forward. This sort of thing won’t get you fired here, but it will get a body into trouble.
Since the lunch area and food fridge is separated from the labs by a badge-activated door, I’m willing to bet that someone forgot their badge and put the sample in a handy place. bleh!
I don’t know, what about, I mean, you know…
Okay, I have got nothing.
Urine trouble now!
Thant’s what he said.
Darling, I have three words for you (well, a word and a hyphenated word): Ex-Lax brownies.
Hmmmm…nobody here practices “urine therapy?”
When my sister and I got our first hamsters, we also got a hamster care book that suggested that, among other treats, hamsters liked powdered milk. I gave my hamster a little dish of it, and she promptly peed in it. Talk about sour milk! I tossed it out and never tried giving it to her again.
In my experience, though, hamsters are extremely stupid, and it wouldn’t surprise me to find out that mice are smarter.
Mice like their pee! They get stressed out without it! Maybe someone in the lab has been amoungst the mice to long . . .
That part amazed me, too. I would have fell off my chair laughing.
BLEURGGHHH!!!
I’ll have the crab juice.
Meh-
We’ve got a freezer full of pee in my office. I’ve been known to put a frozen dinner in there on occasion when the food freezer is full. Doesn’t bother me. The dinner is sealed in its tray, which is sealed in the box, and the pee is sealed in a cup, which is sealed in a bag. That’s four seals between the pee and my food (and pee isn’t dangerous to begin with.)
Even though it doesn’t bother me though, I can understand how it might bother some. Diff’rent strokes.
I didn’t know my straight line would be so successful, but I like Mountain Dew too much to disparage it openly 
Do any of the cups have little wooden sticks poking out of them?
No, urine isn’t particularly dangerous, but as others have mentioned, labs don’t routinely mix samples and food. That’s one of my biggest peeves, watching any kind of medical drama that has people cooking coffee over a bunsen burner or something - that kind of thing is just not done in medical labs (research labs could be different - I couldn’t say). You don’t even chew the end of your pen in a medical lab - the whole lab and everything in it is considered contaminated at all times. Not to mention the “ick” factor - I know pee is not particularly biohazardous, but I still don’t want a bottle of it next to my sandwich.
