The Con Man in the Meth Lab - S4-E9
Continuity mistake: Bones pulls the money out of a paper bag in two stacks. Each stack has 2 elastic bands around it. One at each end. One of these 4 elastic bands is red and the other 3 are brown. When we see a close up of the money the red band has disappeared and now is a brown band. (00:21:00)
