Dipper and Mabel were walking on the boardwalk wearing their swimsuits. Both of them were whistling a tune.

"Alright, Mabel. Let's go to the burger stand to grab some lunch for our girlfriends." Dipper said.

"Sounds like a plan." Mabel said.

Both of them went into the Shack and were greeted by the owner.

"Well, good afternoon lady and gentleman-" he noticed Dipper and Mabel's improper clothing. "Hey! Can't you two read?!"

"Why would you say that-"

"That sign on the door says 'No shirt, no shoes, no service.' I'm trying to run a decent place here."

"Dang it. I thought we could get those burgers." Mabel said.

Soon, the brother and sister looked down at each other.

"Hey, Dipper. Hand me your shorts."

"You hand me your shirt."

The two started fighting. After a while, Dipper stopped it.

"Okay, look. Let's flip a coin and one of us gets to go in and get the food."

"Deal. If heads, you go in. If tails, I go in."

Mabel flipped the coin.

"It's on tails. I go in, now give up your shorts."

Dipper gave up his shorts and was then naked.

Mabel went in and ordered the food. "I would like a double cheeseburger, with fries, and a chocolate milkshake."

She continued as Dipper realized his nudity. "And I would like to take those hot buns!"

Dipper rubbed his butt. "Yeah, good choice. I put oil on them so they don't get burned."

Mabel laughed.

"Alright," Dipper said angrily, "Now hurry up."

Soon, he heard Wendy sing a beach song.

"I can't let them see me like this. Oh no."

Dipper ran into many places on the beach such as under a trash can and in a beach towel.

"Mabel and Dipper were supposed to meet us right here." Pacifica said going near the streetlight.

"Yoo-hoo, Dipper!" Wendy yelled.

Dipper continued hiding while Mabel was laughing.

Hurry up. Dipper thought as he hid behind the streetlight.

Later on, the food was finished and Mabel paid the man $7.85.

"Do you have your ID ready?" The owner asked.

"Sure." Mabel said. The owner saw Mabel's fake ID.

"What, are you kidding me?!" He yelled.

"What?"

"That ID right there is violation of the restaurant code."

Mabel laughed nervously and the owner kicked her out.

"And stay out!"

Dipper grabbed his shorts, and Mabel's shirt.

"Dipper!" Wendy and Pacifica yelled happily.

"Hey, girls. Care to join me in our picnic?"

"Yay!"

Mabel fell down and said "Sorry I'm late."

"Oh my goodness. You're naked in public," Pacifica said. Wendy covered her eyes. "What is wrong with you?!"

"But-"

"Stop, I'm too embarrassed to be seen with you. Now how about that picnic?"

All of them walked away and Dipper whistled.

Mabel was then seen by a crowd that laughs at her.

"Some people just ain't got no class." The owner said scratching his belly button.
