A bit of a lot

First one I remember, I'm part of a family (not mine. The Simpsons, I believe) getting ready for a trip, when this guy that looks and talks like a mixture of Charles Manson and Alan Moore comes in and started harassing us.

Then It jumped to being in a car (with different people) and we were driving around. We passed by a KFC, and I made a joke about black people liking fried chicken.

Then it jumped to some Star Trek convention. Apparently we were all there (I was dressed as Kirk) to see a free screening of the new movie. Some guy explained the general plot, then began to teach us some of the Vulcan sign language.
