"I fixed pheasant" is indeed an American phrase, though I believe it has spread outwith the south (TM even offers to "fix breakfast").
Over here fixing a pheasant might mean splinting a broken wing (unlikely) or trying to recover from overcooking to the point of dry meat.

However, Higgins frequently slips up. Incorrect intonation, the wrong names or grammatical mistakes, it happens at least once every two episodes.
It could be argued that Higgins has been living over there for so long that he's picked up a few Americanisms but its doubtful given that he holds events for the Queen Mother's birthday, QE2's coronation etc and frequently despises some of those "ghastly American customs".

tell you what.....I don't believe i had seen that one since the original run......too many instances within it came to memory so I know I had seen it, but it's cool seeing these episodes that aren't fresh in the mind. I don't think I could've appreciated this episode as a 16 year old, but almost 30 years later it certainly hits me differently. This was a very comfortable episode that I enjoyed just last night.

I will say though.....the flashback scene where Higgins won't accept her help is to me annoying with his over the top genuflecting to the throne as it were......

Could anyone help me with the name of the classical piece that's playing in the background in the scene where Higgins is getting ready for dinner carrying a centerpiece, just before they cut to Magnum getting ready to watch the baseball? Thanks!
