At its finest Perelman's crazily inventive humour makes me laugh out loud (the only other writers who've done so are Waugh, Wodehouse and David Lodge).
The masterpieces for me in this particular collection are: Acres and Pains; Hell in the Gabardines; Dental or Mental, I Say It's Spinach; Take Two Parts Sand, One Part Girl and Stir; The Hand That Cradles the Rock; Westward Ha! (most of it, anyway); Stringing Up Father (in parts); Hell Hath No Fury...and Saks No Brake (in parts); and Danger in the Drains (though direly weak in parts).
But even when the humour fails, Perelman is worth reading for his prose alone, as in: On Me It Looks Wizard; Cloudland Revisited: Rock-a-bye Viscount in the Treetop; The Saucier's Apprentice; Heat Yegg in Vessel and Sprinkle with Hazard; and This Little Piggy Went to Market. This is consistently imaginative, witty, allusive writing that knocks spots off the output of so many feted modern stylists - Perelman is unjustly neglected today.
Of course, as I've indicated, there is much feebleness in this collection, as how could there not be in a regular production of such pieces over 30 years, but the overall standard is remarkably high for a comic writer.
