When Monk witnesses a shooting, he does everything he can to bring the bad guys to justice, but the evidence isn't there. This all takes place as Monk takes a walk, suffering from insomnia. There are so many factors and there are so many wonderful twists and turns, I have decided it is the bet episode I have personally seen. It also has a touching conclusion. There is a great subplot with Randy wearing Captain America pajamas. Stottlemeyer has some great lines.
