MIXED MEDIA : ** “THINGS THAT GO PUMP IN THE NIGHT” Aerosmith, <i> Geffen videocassette ($16.98)</i> : <i> Items in this periodic survey of pop-related books, videocassettes and laser discs are rated on a scale of one star (poor) to five (a classic). </i>

See Aerosmith cavort with nude girls, semi-nude girls, suggestively clad girls and inflatable love dolls. See what singer Steven Tyler’s really like backstage--apparently the same leering goof he is on stage--and wonder why guitarist Joe Perry’s lips never move when he talks. See three recent video clips you’ve seen a couple hundred times apiece on MTV, see how key scenes were filmed, then see the band applauding images of itself after each clip ends. This is pretty thin product. Still, it’s hard to dislike Tyler’s bouncy exuberance, no matter where that exuberance is directed. (The laser-disc version, including a bonus track, is due in stores Thursday and retails for $24.95.)
