"When I see bacon, I see a pig, I see a little friend, and that's why I can't eat it. Simple as that. But I'll eat Linda's veggie bacon. All her food was so good. Steve Martin came around for a barbecue once. I was grilling and he said, “Oh, no, I can’t have any of that.” I asked why not and he said, “Sorry, I’m vegetarian.” I said, “You didn’t know we are?! Everything on the grill is veggie!” He said, “Ahhh” and ate three veggie burgers and then asked where he could buy them."
