S4·E23 Ninja Gaiden

Ninja Gaiden is one of the Nerd's favorite games, but its extreme difficulty has prevented him from beating it. This game is so hard, you'd have to be a ninja to beat it. The Nerd seeks one out, who trains him in the art of overcoming difficulty and sharpens his skills. However, this game might prove to be more than a match for the wise old master.
