Bigger carbon footprints?

I read a couple weeks back that cows supposedly have a huge hand in global warming since they give off so much methane. They are vegetarians too(at least I don't think they feed cows wings, burgers or hotdogs). I also just saw another report that non-vegetarians tend to have more flatulence than vegetarians do. I'm not sure I buy that one. Most of the vegetarians I know can really rip one out and quite often they are able to take down a buffalo with it. I know I get gas every now and then, but never that bad. Eat a burger, you selfish people. You're ruining our environment. I wonder if I can get a grant to study this. They're wasting our tax dollars on everything else, why not this important piece of the global warming puzzle. I guess I'll put in for the grant after the 20th. Who knows, maybe I won't have to do real work anymore then. Just study farts. The downside would be that I don't think there'd be a good pickup line for the women at the bars in there. 'What do you do for a living?' ummmm.... nah, I really just better stop and go to bed now.
