Well, then...

I got a new book of flute trios in lessons yesterday. The front of the book reads,

Six Trios for Three Flutes

(Or three clarinets, three saxophones,

or other similar like-instruments)

My first thought was something like, "Ha ha, 'similar like-instruments'. Why not say 'woodwinds'. And then I saw that it specifies that the trios are for three instruments. Wow, a trio for three!!;)
