OK, just had a thought--I've never watched Hamish MacBeth, but how about this for a crossover--Father Ted/Snarry? Have you seen that show? I would love to see Snape dealing with the shenanigans on Craggy Island, not to mention dealing with the endless offers of cups of tea from Mrs. Doyle. Anyway, that was a random silly thought you might appreciate!
I'm also inspired to read Captains Courageous! I haven't read Kipling in years and years. I loved how you created the analogies between the stories Severus read and his thoughts and the arcs of his and Harry's lives. Just great.
