The cave-fratboys give BB its bad rep (and it always reminds me of Chesterton's comment that the one thing we know about cavemen is that they could paint, referring to the caves of Lescaux), but amid the funny, it gives the mike to Maggie Walsh and lets her tell us, indirectly, what she is about -- and what the whole conflict is going of the season is going to be, that is, the apparently rational forces of science & control being subborned by everlasting primeval forces, and being confronted by the apparently non-rational, but actual trans-rational force represented by the friendship that binds Buffy, Xander, Willow & Giles into a (S5 theme please) family.
