Continuity mistake: When T and Texas Blood are playing pool, the balls would move around after the stopped. Most notably after T makes the 1-ball. The cue ball is on the opposite side of the dot than the 8-ball and the other two balls are on the other end. In the next shot, the cue ball is on the same side as the 8-ball and the other two balls are now close to the cue ball.
Mr. T: You know what's bothering me? Two things. One is I'm sorry that I can't sue you for false arrest. And the other is, there's no toilet paper in this cell.
