Take this piece on blurbs with a grain of salt because it’s coming from the New York Post, journalism’s retarded lovechild (born to a facile, ranting religious right pamphlet of a mother and fourth grade dropout, celebrity-stalking father), but it has Jonathan Ames in it, and I kind of dig his schtick.

Come July, a new book will come out called “Up for Renewal,” about bettering life through magazines.

On the back of it will include the following quote: “You know that warm, relaxed, pleasurable feeling you get when cracking open the latest issue of your favorite magazine? That’s what reading Cathy Alter’s ‘Up for Renewal’ is like. Prepare to . . . get truly inspired.”

And I meant every hyperbolic word of it. See, sometimes you can judge a book by its blurber.

“I have no idea at this point how many books I’ve blurbed,” says humorist Jonathan Ames, who is approached frequently to dish out book-jacket praise.

“It may be about 50. It might make some long, strange poem if I was to collect them all.”

In fact, one of his blurbs was even declared “best blurb” by New York magazine for “The Only Bush I Trust Is My Own,” which Ames notes, “on the title alone, deserved a great blurb.”

While he tries to blurb honestly, he does admit, “Once I promised someone that I would blurb their book, and then I read it and didn’t feel so strongly about it. This was years ago. But I blurbed it anyway, and then a fan e-mailed me and said they bought the book because of my blurb and were sorely disappointed. I felt bad about this. But I guess it shows that blurbs actually do work once in a while.”
