folds on Five Dollar bill for joke - Fold the bill on the lines away from you, then unfold. Between the two creases make a kind of trough, but not so deep that it obscures the area between the folds. Now with the person facing the bill directly, say 'Say 'Hi' to Abe.' When the person greets Abe, tilt the bill so that the top is slightly away from the viewer. Then say, 'Ask him how he feels about Mr. Bush.' When the person asks that, tilt the bill so that top is slightly toward the viewer.
