Right before Todd introduces the tan-lines dance routine, he says something that annoys the crowd. The people in the crowd express their annoyance by hurling literally dozens and dozens of paper cups and other objects at him, which land around Todd on the pink dance platform. Then the camera angle changes as the first girl comes on the dance platform, yet there are no paper cups or any other debris visible on the dance platform.
After Todd enters the dressing room with the large breasted blonde woman, he begins smiling and making faces at his brother Alan through the two-way mirror. Although Todd does this behind her back, she would obviously be able to see what he is doing in their reflection since they are both facing the mirror.
After Todd says something to annoy the crowd, they throw garbage at him. During the close-up you can clearly see three cameras zooming back and forth in the reflection of the window.
