i loved the garden paradise on his roof, too, where Paul McCartney wandered. i especially remember Lisa mentioning she consumes dairy and Apu mentioning he doesn't. Lisa said something like, "You must think I'm a barbarian." Apu responded, "Yes," but that he must tolerate her choice.
it's funny that none of the characters know the hot dogs are vegan...when i consumed a vegan hot dog i blanched. i love veggie burgers and faux chicken, but hot dogs never tasted right. still, i like the idea.
