The floors are tiled. The walls are wood-paneled. And there are many maroon doors, all numbered, from 1 to 10. These could be the basement offices of part-time faculty members at some community college. But what's up with all that moaning? Is it the audible expression of higher minds at work? The sound of curious human creatures plunging for knowledge? Well, sorta. It's porn. This is Adult Video World. And these rooms are 50-cent-per-minute "private viewing booths," where self-educated professors of the pornographic arts are carefully analyzing 60 channels' worth of cinematic smut, refreshed on a weekly basis as part of this institution's ongoing "XXX video arcade" program. Of course, if one prefers to pursue his or her masturbatory endeavors in the comfort of a home study, AVW also boasts a library of 6,000 DVDs, catalogued according to genre — from young or old to chunky, lesbian, and classic — all available "for rental and sale at great prices!"
