Foaming/Arny H.A.T. single

[Stonergrunge]

Hi! so, after a couple of weeks I could finally listen to this 7 inch properly. In the very end of "Arny" there's what it seems to be the endless loop of a voice, and because my turntable is not automatic I kept listening to it over and over thinking "well, now is going to stop" but then I recalled the ending of another record (Sgt. Pepper's from The Beatles) where there's also an endless loop. So am I right and the Melvins are just playing with me or what?

It's a lock groove, probably done on purpose.
