Sometimes you get the bear, and sometimes the bear gets you. But it’s hard to tell who won in “Crap Taxidermy” (Ten Speed, $12.99). It’s a new photo book drawn from Kat Su’s ghoulishly hilarious Web site, CrappyTaxidermy.com. This is not be confused with Adam Cornish’s Web site, CrapTaxidermy.com, which this month has inspired its own equally surreal photo book, “Much Ado about Stuffing” (Andrews McMeel, $9.99).
