"It was the best of pairings it was the worst of pairings"

[lm]

If you had to rank each potential male/female romantic pairing (yes, even putting aside the Howells' marriage, bad as that may be)--including every possible combination of one male and one female in any romantic way and rank them according to the "likelihood" of something arising (in any way) between them--which pair would be at the TOP of your list and which would be at the BOTTOM? Do not go by whom you would LIKE to see together but by what the show would lead us to vote as likely or unlikely, given the characters' actual interest and ideas about each other. Which is your choice for the Most Likely and Least Likely romantic (in any form) pairing?
