The 'Sorry, Force Of Habit' meme originates from the animated film Phineas and Ferb the Movie: Across the 2nd Dimension, featuring the character Dr. Heinz Doofenshmirtz. In the scene, Doofenshmirtz reflexively performs a villainous action or makes a comment, only to immediately apologize by explaining it's a 'force of habit.' The template gained significant traction on platforms like Reddit and Twitter as a way to illustrate social awkwardness or muscle memory gone wrong. It perfectly captures those cringeworthy moments where we respond to a 'Happy Birthday' with 'You too!' or try to use a turn signal while walking down a hallway.
