U.S. Rep.-turned Governor-turned secretary for homeland security-turned natural gas industry consultant Tom Ridge appeared last night on Comedy Central's The Colbert Report to talk about the practice of "fracking," forcing water, sand and chemicals into the ground at great pressure to break up shale deposits and tap pockets of natural gas.

Ridge started strong on his talking points but had a long pause, put down his head, held up his hand and then pressed on after host Stephen Colbert asked this about the chemicals pumped into the ground: "How many of those can I feed my toddler?  Because it's perfectly safe, right? It's perfectly safe?"

"Well, you'd be abusing your kids if you did," Ridge replied. "So let's just put that away."
