Monkeys taught how to gamble and play video games. People paid to watch grass grow. Swedish massages given to rabbits. These are just a few examples from the 100 entry-long list in a book detailing government waste, compiled by retiring GOP Sen. Tom Coburn of Oklahoma. In the 2014 edition of the Wastebook," Coburn notes that getting rid of the practice of pork barrel spending is next to impossible. "What I have learned from these experiences is Washington will never change itself," he said." Some of the worst offenses listed in the book: The $1 billion price tag the Pentagon paid to destroy $16 billion worth of ammunition, enough to pay a full years' salary for over 54,000 Army privates. The book cites Pentagon officials who said the surplus ammunition has become "obsolete, unusable, or their use is banned by international treaty." The Army spent nearly half a million dollars -- $414,000 -- to develop a video game called "America's Army," a version of which terrorists have used to train for missions, according to National Security Agency e-mails sent in 2007 and leaked by former NSA contractor Edward Snowden. Coburn notes ... the national debt, which is "quickly approaching $18 trillion."
