Oh my Frond, the not-poison one... XD
Two for you:
#Deduce things about people (Sherlock-style :D )
#Make a chart about bloodstains
I found the latter out the hard way. In maths, my maths teacher decided that we should practice making charts, and he got us all to get into groups and make charts. My group is incredibly lazy, so we decided that we would all just make a graph, write a bit about it, and stick it on some paper.
I couldn't think about anything to make a graph of, and then I remembered: a couple of years ago, I went to this short forensics course. Basically, I ended up with some unnecessary information about how bloodstains spread out as they fall from different heights... And also the graph of what this looks like.
So I did a graph on bloodstains. And then we had to explain our posters. I didn't get through the first sentence of my explanation; half of the class were giggling madly (including me) and the other half were staring nervously at me. Now they think I'm a psychopath, when I just have a really weird memory.
I never got the chance to explain that it was tested with paint.
