According to sources on the set, Top Chef host Padma Lakshmi often indulged in a joint on the set every now and then -- or, you know, "fairly regularly." As the Best Week Ever folks point out, this explains a lot, like how she usually seems only marginally involved in whatever's going on, how she speaks very slowly, and how she married Salman Rushdie.
It's also disappointing, though, because we could have pushed this storyline much further. Pot brownies have been done -- can we see someone attempt a duo of Mary Jane foie gras and sirloin? With pot potatoes on the side? Can Marcel make a foam out of it? Or mix it with xantham gum? I can't believe no one thought to try that. It would have made for one hell of a judges table.
