Eating only Canned food on their mystery tour

On their BS show, I believe Penn tells us they have never even had beer. They do seem to be almost religiously particular about what they eat and drink. Maybe that helps keep them sane in Vegas, and less likely to die during a dangerous trick. I hope at some point they'll lighten up. It would be a shame to never experience beer or wine or mixed drink.

Still, I can't fault anyone for not trying local food in poor areas of foreign countries. Though the food may be delicious, or at least interesting, travelers do not have the immunity to local disease. A pleasure trip is one thing, but if you're expected to be creating a show, you can't get sick.
