"again"? you mean he hasn't been locked up yet for raping inanimate objects? hohoho... *cough*
Dude, google up "The Real Frank Zappa Book" and you'll eventually land on an HTML version of the book. There's an episode there about Steve Vai using inanimate objects with a woman name Laura (Laurel). The episode even includes a scene with Steve drooling on his own dork.
Check out the lyrics of the song "Stevie's Spanking". It's the penultimate FZ tribute to Vai's engagement with inanimate things.
