The Hawker Fury was a sleek-looking British biplane fighter of the 1930s.  My first thought was to post "Billy".  (Does everyone remember Billy Fury?  In the 1960s, I owned his "Fools' Errand" as a 45 -- I don't mean to boast, but I did.)  But I scrapped "Billy" because I recently posted "Billies" on this thread, and thought that "Billy" would have us going round in circles.

The lyric of "Fools' Errand" goes:

Did my my heart send me on a fools' errand when it sent me after you

I once had a mondegreen of this that went:

Did my my heart send me on a fools' errand on a Saturday afternoon

Actually, to fit the tune, more "Sat'day afternoon" than "Saturday afternoon".

Of course, it might have been on a Saturday afternoon that his heart sent him after the person in question.

I wonder whether this is the longest post in this thread.  Most of them seem to be a lot shorter.
