On April Fools' Day Tadashi is once again in his original Swag Meister clothing. Hiro walks in with (y/n) to see Tadashi staring intently at the two.

"Umm, what?" (Y/n) wonders looking at Hiro for an explanation. Hiro sighs.

"I am so done with you Tadashi!" Tadashi turns around then moonwalks next to Hiro.

"Li'l bro," he says. "Embrace how awesomely swagtastic I am! Feel the power of the swag surge between us as I grasp your shoulders!" He clamps his hands on Hiro's shoulders. Hiro attempts to wiggle away from Tadashi's powerful grip. (Y/n) stares at the scene unfolding and wonders when on Earth Tadashi had become like this. "Do you feel the swag?"

"No! Dammit Tadashi let go of me!" Hiro yells. (Y/n) bursts out laughing.

"Hiro!" Tadashi shouts. "(Y/n)!" He swaggers over to them. "I have something so important to tell you!" He showers them with glitter and colorful confetti.

"What the hell?" (Y/n) wonders. Tadashi keeps throwing confetti. "No seriously, what the actual fuck?"

"I'm a Swag Meister!" Tadashi leaves, still tossing confetti and glitter.

"What?"

"I still can't explain," Hiro mutters, shaking his head.

At the end of the day, after more Swag Meister randomness, Tadashi comes into the bedroom where Hiro and (y/n) are talking.

"No! Not again!" Hiro shouts. "I still have glitter everywhere!" Tadashi comes very close to both and whispers...

"April Fools'!!" (Y/n) starts laughing so hard that tears well up in her eyes and she doubles over. Hiro starts hitting his older brother.

"Damn you big brother!"

In this way (y/n) never found out the Tadashi actually believes that he is the swaggiest of Swag Meisters ever.
