Sonic & Knuckles Effect

The Sonic & Knuckles Effect only happens when 2 characters are compared to each other. One character may have more careless, goofy, "radical" behavior, and the other character may have serious and focused behavior. The original form of the Sonic & Knuckles Effect was, well, Sonic & Knuckles, with Sonic being the more careless character, and Knuckles being the more serious character.

Person 1: Hey! Cmon, what are you doing here just sitting around?
Person 2: I'm trying to look after my belongings.
Person 3: It looks like you two have the Sonic & Knuckles Effect
