"just yesterday, a caller named tom from philly called the rush limbaugh show and had a heated discussion about global warming. tom totally pwned rush, first by congratulating rush for being able to turn bologna into $400 million. Rush wanted to know what was bologna, and tom mentioned global warming, to which rush blew his cork, calling it a myth, saying there was no way that man activities could ever affect the climate (dust bowl?, acid rain? PCBs?). Tom asked rush what his credentials were to evaluate the science of climate change, which rush shot back that inquiring about credentials (when presenting yourself as an expert) was "elitist". Tom pretty much mopped the floor with rush, until rush cut his mic and then proceeded to insult tom, who could no longer defend himself. yeah rush, things we do DO have an effect on the environment. if you ever have a doubt, there is a real easy experiment that will prove or disprove this fact. pull that SUV into the garage, leave it running, close..." - polymath22
