“What animal can be found in the unemployment line?”/“The poorqueuepine.”

A “porcupine” (a mammal) has nothing to do with a “poor queue,” but there have been puns. “A prickly tree standing in line with other trees waiting for a handout during the Depression: A poor queue pine!” was posted on the newsgroup alt.humor on July 2, 2007.

Wikipedia: Porcupine
Porcupines are rodentian mammals with a coat of sharp spines, or quills, that protect against predators. The term covers two families of animals, the Old World porcupines of family Hystricidae, and the New World porcupines of family Erethizontidae. Both families belong to the infraorder Hystricognathi within the profoundly diverse order Rodentia and display superficially similar coats of quills: despite this, the two groups are distinct from each other and are not closely related to each other within the Hystricognathi.
