When taking objects to your hands from the player menu (ex.: Nerfy Gun, Confetti Gun, etc.), it is possible to take the same object again in the other hand.

Doing this and trying to store them back will cause the game behave oddly for the second hand, leaving the object floating in mid-air instead of disappearing.

The object can be picked up again, but is now permanently stuck to your hand.

This can be combined with another glitch specific to the controller object, allowing you to create extra hands to pick up different objects with.
