Someone on that last Holmes and Watson movie pulled a good one

The movie is Game of Shadows, and there's a scene where, while everyone else is riding a horse, Holmes is on a pony.

And as they're riding, the music for the scene is the theme from Two Mules for Sister Sara*.  I thought it fitting.*

*In case I've overly dated myself by mentioning a western nobody else remembers, Sara starts off with a mule which goes lame, and she trades it for a burro.   Now go watch it
