Finally, a sound explanation for dinosaurs' extinction: their obsession with cavemen's underpants led to "a great briefs tug-of-war," during which the dinos were done in. It's all so hilariously ridiculous that readers won't mind if Freedman's rhymes sometimes lose the beat. Cort employs some fierce colors in his amusing illustrations of underwear-clad men and beasts.

PreS-Freedman and Cort offer another homage to underpants. Cartoons in bright colors and patterns pep up the rhymed tale that explains the demise of dinosaurs. According to Freedman, "When T. rex saw man's undies,/He roared with deafening rants./I don't want to eat you up./I want your underpants." All dinosaurs follow the obsessive fad, escalating to a manic dino tug-of-war that wipes out every order, saving mankind. Despite the skimpy plot, preschoolers will giggle as itchy or tight briefs annoy Stegosaurus or Diplodocus, while theft victim cavemen shyly cover up with huge leaves or the few remaining pairs of underwear.-Gay Lynn Van Vleck, Henrico County Library, Glen Allen, VA (c) Copyright 2010.

The author and illustrator of Aliens Love Underpants (2007) go to the well again, describing in stumbling verse and colorful but unexceptional art how the dinos wiped themselves out squabbling over their prehistoric panties. Seeing cavemen modeling newly invented fur boxer shorts, the envious dinosaurs steal the concept, but they discover certain design flaws: "The pants from Woolly Mammoth coats / Made Stegosaurus itchy. / Diplodocus was really mad. / His briefs were way too pinchy!" Irritation quickly escalates into fury, and the ensuing autogenocide both leaves the cavemen (there are no women in evidence) relieved and leads to a closing "Don't forget briefs saved Mankind. / They're not just underwear!" Children may find Cort's cartoon pictures of big, grumpy-looking dinosaurs sporting undies loud with polka-dots and other patterns briefly (so to speak) amusing.

As long as you can suspend all sense of evolution, literature, and good taste and are of a single-digit age, you'll crack up with hysterics at this theory of dinosaur extinction from the creators of Aliens Love Underpants (2007). According to the story, cavemen began to feel embarrassed in the nude, and so they dreamed up underpants, which the dinos coveted and copied, creating a mass frenzy that escalated into a Mighty Underpants War and the end of the giant beasts. Once again, the rhyming text and illustrations turn this into a comic delight.--Medlar, Andrew Copyright 2009 Booklist

Fans of Aliens Wear Underpants will revel in this companion volume's dotty humor and pell-mell action. The tongue-in-cheek story purports to solve the mystery of why dinosaurs disappeared, and the slapstick illustrations are filled with details to tickle a dino-sized funny bone. Cort pictures a circle of bearded cavemen (including one holding a well-placed fig leaf) watching underwear being invented by one of their companions, who wears leopard-print briefs. The primary colored dinosaurs quickly become underwear obsessed, and sport underwear decorated with flowers, swirls, and wooly mammoth fur, which causes all manner of problems (including fighting over who gets to wear what). The rhythmical pattern of Freedman's text sometimes breaks down, and her rhymes are occasionally slant ("itchy" rhymes with "pinchy"). But the overstated humor of the illustrations is infectious as, in the end, the dinosaur "fighting got so crazy,/ All the dinos were wiped out!" Closing illustrations feature a modern boy putting on dinosaur-decorated briefs while the narrator cautions to treat undies "with great care./ Don't forget briefs saved Mankind./ They're not just underwear!"
