I REALLY like Penn and Teller as people and for what they do, but their show in PETA and their show on Second Hand Smoke both made me mad. In the Smoke episode, they came to the conclusion that SHS wasn't at all harmful because it probably didn't cause cancer...ignoring the fact that the jury is still out on the cancer issue, there's also the allergy issue and the disgustingness issue. They're great guys, but the show often proves one point by ignoring the rest.
