Joe Fox takes the two kids to a street fair. There is a part when the little girl is throwing rings around bottles. Watch carefully, she throws the ring and it's red, but when it lands it's green. weird. watch, you'll catch it.
Yes, this is a real one. Chapter 8 on the DVD. What's better is that there are more than the one ring changing colors. When he hands her the red ring, he also has a green and a yellow one in his left hand. He takes the green one, the shot changes, and then ring is yellow that he's handing his brother (on his shoulders). As his right hand comes back down, it now has a red ring in it. You then see the girl throw a red ring, a green one lands on the bottle, and Tom stands with a yellow ring in hand, but the little boy has none.
