Nerd Rage!

Nerd Rage! is a Fallout 3 Perk.
 * Requirements: Level 10, Science 50%
 * Ranks: 1
 * Benefit: You've been pushed around long enough! With the Nerd Rage! perk, your Strength is raised to 10 and you gain 50% to damage resistance whenever your Health drops to 20% or below.

Note that both effects, Strength and DR, only come into play while your Health is 20% or less.

This is a reference to The Incredible Hulk.
