When I was a n00b in the lab, my rotation project was to clone our gene of interest into a dsRed vector, but I had to clone in an acceptor site, and put a 3X flag in the sequence. Because this was hard for a N00b, it took me 6 weeks, and I went through a lot of agar plates. (after 6 months in the lab, the same damn thing took me a week, and I felt like a prize idiot) I also had to make agar plates for everyone else, as dictated by my lab overlord Dave.

Dave was cool. He flat out told me not to join the lab, and he was actually the one that came up with 'Jackass' as the PI's nickname.

So, one day, I made some agar plates (from a mix, no less), let them solidify while I was at class, then came back and put each individual plate into the sleeve that they came in. I then took them across the lab, and put them in the crisper section of the fridge.

Go back and read the previous paragraph again. I'll wait.

2 days later, I'm sitting at the lab bench. Dave goes to grab some plates out of the fridge, and all I hear is "Holy Fuck! What the hell did you do?" I walk around to the fridge, and Dave is standing there with the sleeve of plates, and all of the agar has un-solidified and is soupy in the bottom of the plastic sleeve. Dave is laughing his ass off.

I start explaining that they were solid when I put them away. They had to be, because there was no way I was getting them into the bag if they were still liquid. So Dave starts harassing me. He starts asking how I got something to unsolidify in the fridge. He starts telling me that I should transfer to physics because I have a future in cold fusion.

Neither of us ever figured this out. It never happened again.
