Deceptive Family Introduction

Explanation
Experiment
The person in the joke sets up a scenario where both his mother and girlfriend will have an inaccurate view of each other's capabilities, leading to potentially awkward or funny interactions. He tells the girlfriend to speak loudly to his 'deaf' mother, and tells the mother his girlfriend is 'disabled'. It's a prank based on deception.
