Locker room puzzle

[mtbc]

Some of the lockers at my gym have a horizontal bar near the top for clothes hangers. The hangers are of the kind one often sees in hotels: the large triangular part easily detaches from a smaller component that hangs on the bar.

While I was putting my clothes in my locker there was a clatter and the main part of a hanger appeared in there, atop my pile of clothes. But, there was no sign of the hanger's top part. I suppose that sometimes the Matrix glitches.
