Do it!
I once appeared on a radio talk show in Boston. The guests that evening included a woman who claimed to have been abducted repeatedly by aliens (levitation, cavity probes, the usual), her husband, and some guy who wrote a book about it. It also included J. Allen Hynek, the semi-famous UFO investigator. The host wanted a skeptic who was fairly knowledgeable about astronomy, and to make a long story short he ended up with me. (He actually wanted Carl Sagan, but his fee was too high!) It was actually pretty easy to poke holes in their arguments since the woman was clearly deluded (she spoke for something like 40 uninterrupted minutes describing her experiences in minute detail, in a dreamy, ethereal voice that still gives me the creeps). The husband and the writer were basically trying to make a buck off her delusions, so I really didn't have a great deal of respect for them.
The only one who sounded remotely reasonable was Dr. Hynek, in what may have been one of his last public appearances (he died a few months later). I asked Dr. Hynek how he could explain why it appeared that there were so many different species of aliens visiting the Earth, using so many different types of technologies. Did he really think there were that many different civilizations visiting us? And if so, why were we so damned interesting? Dr. Hynek gave an interesting reply -- he stated that he no longer believed UFO's came from different planets. Instead, he thought they may be visitors from different dimensions. I found it ironic that one of the leading proponents of the E.T. theory (in fact, he briefly appeared in the Spielberg movie “Close Encounters of the Third Kind,†a phrase he coined) ultimately came to reject the idea that E.T.’s existed.
Anyway, it was great fun and basically if you can stay calm you’ll do fine. Just try not to get too angry when they start insulting your intelligence!
