[*Four frame cartoon. In every frame Joe and Paul are walking along outside as they talk. Frame 1 - Joe says to Paul "Wherever we go there we are." Frame 2 - Paul replies "Obviously Joe." Frame 3 - A speech bubble appears well behind both of them, as if it's just coming from the air. The speech bubble contains Joe's reply of "It's not always obvious Paul." Frame 4 - Paul looks over his shoulder at where the reply came from and says "What the heck!?" Joe glances at Paul with a smile on his face.*]
