We kind of fast forwarded through the first part of the movie, but it begins in some kind of desert market - I have no idea what happens but it results in a group of arab dudes chasing Phoebe and Willie through the desert.
People want a well oiled, loin cloth wearing with occasional full frontal nudity.
Eventually they find an Oasis in the desert and Willie builds them a goddamn split level ranch or some shit.
Then the chimps have a baby, which is inexplicably a baboon.
