"It's summer!" Mario yelled. He ripped off his shirt and dove into the pool. That means he had on overalls but no shirt.

Luigi came over in a real bathing suit. "Mario, you're a bit mixed up." He said.

"No, I'm not." Mario replied, strumming his overall straps like a banjo.

"That's weird, stop doing it." Luigi replied.

"I'm swimming go away!" Mario yelled, making a spring.

"No, because I am swimming too!" Luigi replied, diving in.

"You stink like a sewer," Mario told him.

"Well, you stink like Wario." Luigi replied.

"How dare you! Take that back!" Mario yelled.

"Never!" Luigi yelled.

"Fine, I'll just have to tell the princess you said that I stink like Wario." He said.

"Well, I'm gonna tell her that you said I stink like a sewer because you started it!" Luigi replied.

"Well, I'll get to her first and you'll be busted!" Mario yelled, getting out of the pool.

"I'm faster, and you'll be busted instead!" Luigi said, shooting ahead of Mario. They bumped into the princess suddenly.

"What are you two doing??! I'm trying to walk here! Gees, I guess I just can't swim anymore," she said, walking past them.

"If you hadn't raced me, we wouldn't have bumped into her!" Mario yelled at Luigi.

"Well, if you hadn't started that fight, we would be peacefully swimming right now!" Luigi yelled back.

"Hmph." Mario replied. He ran over to the pool and dove into it. Luigi came in too.

"I'm gonna murder you!" Mario suddenly yelled, pushing Luigi underwater.

"I can breathe, you know!" Luigi bubbled.

"Hmph." Mario said, letting Luigi up.

"You're a cold-blooded killer." Luigi told Mario.

"Well, you're a warm-blooded liver," Mario replied.

"That makes zero sense," Luigi said.

"Well, you're the worst brother ever!" Mario yelled. Everybody within earshot gasped.

"You're even worse than worst!" Luigi yelled back at Mario. Nobody really gasped besides Mario. Then he started crying.

"You're so awful, someday you'll get bitten by a tarantula!" Mario cried at Luigi.

"Well, it's about time somebody started crying around here." Luigi replied, getting out of the pool. He tromped inside the castle.

Then Blue Toad came over. He bobbed on the water next to Mario. "What's up?" he asked.

"Nothing," Mario grumbled.

Blue Toad looked puzzled. "Okay." He replied.
