The 'Interesting' meme features Megan Parker, the mischievous younger sister from the hit Nickelodeon sitcom Drake & Josh. The iconic frame captures Megan sitting at a computer, holding a juice box, and peering suspiciously at the screen after discovering one of her brothers' secrets. It became a viral sensation as a reaction image used to express suspicion, cynicism, or the discovery of something scandalous. Today, it remains one of the most popular ways to respond to ironic situations or 'shady' behavior online.
