The Gilbert & Sullivan opera "Ruddigore" was originally titled "Ruddygore".
People actually refused to see it because of the resemblance of "ruddy" to
"bloody". So Gilbert changed the name.

When someone asked Gilbert "How's old 'Bloodygore' coming?", he replied "If I
say I like your ruddy complexion -- which I do -- it does not mean I like your
bloody cheek -- which I don't!"
