S-A-I-N-T Prototype Number 1 is the "leader" of the S-A-I-N-T robot
prototypes proposed by Nova Laboratories in Short Circuit.
When Nova lets loose Number 1 and his "brothers" on Number 5, the sentient robot uses his smarts to outwit them. When dealing with Number 1, he threw some mud right into its eyes, blinding its vision long enough for Number 5 to shut him down.
Number 1 is then reprogramed by Number 5 to act like Moe Howard of the Three Stooges. Mud is shown on top of Number 1's helmet to look more like Moe's signature "bowl cut".
