At first I thought those separate previews were all one long show. LIke Christina Applegate was somehow involved with one of the cavemen and the lives of the carpoolers were somehow going to entwine with those of the Cavemen during their drive, "Crash" style. Like Cavemen was going to be some Altman-esque portrait of Los Angeles. Encino Man meets Grand Canyon.
My favorite part of the whole CaveMan phenomenon is how it's a big joke about how stupid it is to be sensitive about your heritage and ethnic identity and how racism is actually funny and you shouldn't care about it.
