This recent CollegeHumor video appealed to me (they usually do but this one more than usual):
I can understand the frustration of being isolated from the main group at a social outing, as it means you lose out on the friendship circle that forms for the duration of the outing and beyond. This has happened to me and in such cases, I've been grouped with either a person or people who didn't want to talk or worse, was grouped with no one at all. This made fitting in with everyone else extremely difficult, at best.
On the other hand, in the case of a road group, being in the "boring" car may not be much a bad thing, for there's less of a chance of the driver being distracted by any funny business"
This particular video is the first in a multi-part series to do with something else but holds its own as a standalone video.
