I thought I'd revive this thread with the first HJ I received. My biology lab partner was a real cutie who I would have loved to date, but she was 'not into that', all of her energy went into getting accepted into med school. She kept a 4.0 average and studied with every waking moment. I missed class one day and she said she's meet me at the lab that afternoon to go over what I missed, she didn't want to chance me messing up her grade.

So we meet and go through some slides, the lab was deserted on a Friday afternoon, and I mentioned how boring this stuff is, and I had a lot more fun with my first microscope. She asked 'how do you have fun with a microscope?'
I told her by looking at my semen samples to see the little guys swimming around. She laughed and called me a pervert, but she was intrigued.

Scientific curiosity got the best of her, she ended up getting a sample from me that afternoon and loved watching the swimmers.
