I remember after one meeting where I took on a project no one else wanted (including me). The room emptied until the only two people left were my boss and I. We looked at each other and didn't have a clue what just happened. After a minute or so of silence, he shrugged his head, left and turned out the lights!!! I sat there in the darkness contemplating retirement.
I love this one even though it brings back some bad memories.
(Yoric, don't forget that they were breaking up into small groups. Dilbert probably took his "group" to another room. The carpet color changed as well, from blue to green.)
