Second time around (even third, for some chapters), it is just as funny as before. Coren died not long ago, and was justly praised for his long association with Punch (also RIP), when it was still a great dentist's office distractor. Some details (prices, salaries, typewriters) are long gone, but just minor time-blips that remind of the days when the articles were written (1960s, mostly).
Most (all?) of the 30-odd pieces are from his Punch days - each about 5 pages long, which makes for easy dipping. If you like puns, wicked satire (you don't have to be Brit to get it, but occasionally it helps), self-deprecating humor, zeugmas, and sundry other word-playing mental gymnastics, this is well worth hunting for.
