If you crouch and right click a Strider to ride it, you will not move as expected, however, the Strider's health bar can be seen for a brief time (less than a second), and the Striders head snaps back like it would when you're riding it. When you do this multiple times, you will find you are unable to ride the Strider anymore until you crouch again. If you do this and walk away from the Strider and crouch, you will be teleported back to the place that you right clicked the Strider while crouching.
