The 'I Worry About You Sometimes Candace' meme originates from the hit Disney Channel animated series Phineas and Ferb. It features the optimistic Phineas Flynn looking at his older sister Candace with a look of genuine concern after one of her many frantic attempts to 'bust' him and his brother. The template gained massive traction as a reaction image used to respond to people sharing bizarre personal facts, strange intrusive thoughts, or overly specific anecdotes. It perfectly balances the line between sibling affection and the realization that the other person might be losing their mind, making it a staple for internet users documenting their most chaotic social interactions.
