Seriously?! is this even a question?! That would be a resounding yes!!!!!
Why?
Well, for starters, just look at these nice green/grey robes I'm wearing. I'm a proud member of House Slytherin, and Professor Snape was Slytherin's Head of House, so it goes without saying that I would wish to support him. But, believe it or not, Slytherin Pride is not the only reason I would choose to take his class. Underneath these robes of green there lies a lining of blue and bronze. I have enough Ravenclaw tendencies that I enjoy learning, and I enjoy a challenge while doing so. Snape seems like he would have been an exacting Professor, one who demanded the very best from his students. I can respect and admire that.
In Muggle terms, I love chemisty, and Potions is rather the magical equivalent of that. If not for my calling as a Healer (paramedic), I do believe that I would have loved to pursue the career of Potioneer (chemist). It rather suits my nature, I believe. Who knows, maybe one day when I'm old and grey, I just might do that!
And I won't even try to lie. One of the real reasons I would love to be in Snape's class can be summed up in two little words...
