The Crossing Guard

When Milo and Lizbeth tries to cross the road to get to Ruth-Ann's, the crossing guard forbids them as they need a group of three people to stop traffic to cross. Hilarity Ensues every time they cross back and forth (due to Milo catching up with his homework during every commercial break) such as using Max as the third person to cross, Milo using a rod to force the guard to stop traffic, and tricking the guard by claiming that he has giant tarantula under his arm.
