Who says environmentalists don't have a sense of humor?This just in from Grist: Elvis goes green. Yes, Kansas City has its very own Eco-Elvis, a green-jumpsuited performer ready to pelvic-thrust his way into your party or event. He's written new lyrics to Elvis tunes to spread his environmental message.You'd want to flick your Bic for "Can't Help Recycling it All." But of course, "Viva Las Vegans" probably brings the house down.
