The 'Success Kid' meme originated from a photograph of a baby. The baby's pose and expression were just so perfect for representing success. It's like he's saying 'I've got this' or 'I've achieved something great'. As the internet loves to use images to express emotions and situations, this photo was a natural fit. It can be used when you finally finish a difficult project at work, or when you reach a fitness goal. It has become a popular way to share feelings of accomplishment and pride, and it all started from that one photo of the baby with his fist of sand.
The 'Distracted Boyfriend' meme originated from a stock photo. In the photo, a man is walking with his girlfriend but looking back at another woman. It quickly became a meme because it could be used to represent various situations where someone is distracted or unfaithful in a humorous way, like being distracted from work by something more interesting or being tempted away from one choice by another.

His nose shoots out lasers to light the way instead of just glowing.
