Marius didn't know how Courfeyrac talked him into doing this, but he's walking down the supermarket aisles casually with two gallons of milk in each hand and contemplating his life choices. He glances around at the other customers going about their day calmly, picking out what they need for groceries and such. Does he really want to do this? There was no turning back now. He can see Courfeyrac pretending to rifle through some of the chilled meats among the other customers, with Grantaire doing the same a few feet away. They kept a cool, calm demeanor as if they were just another few customers wanting to get shopping over with.
When Marius thought it was the right time, he suddenly started to run, after a few feet or so he flung the two gallons of milk to the floor. Milk went flying everywhere, covering the tile floor only for the brunette to fall right into it with a thud. The customers hanging around instantly reacted when the milk cartons hit the floor and some of the milk spray hit them; dropping whatever they were doing to turn around and gape at the teen on the floor, groaning in pain in the huge puddle of milk.
Grantaire and Courfeyrac had to try so hard not to laugh as they put a look of concern on their faces. They rushed over to Marius, each taking hold of an arm and hoisting Marius up out of the milk. It was a failure, though, for Marius kept slipping and sliding in the milk, customers now crowded and chattering loudly around the three stupid teenagers.
"Woah, woah, woah," Courfeyrac had muttered, pulling Marius up by the arm he had in his hold. The male still slid in the liquid, now covered in it, all over his clothes. He was sure it was going to be a very uncomfortable ride home.
Just when they got Marius halfway up, they all had slid down into a pile, splashing the milk everywhere. Grantaire had landed on top of them, Courfeyrac sandwiched in the middle of the two of them. All of them struggled to get up, but to no avail; they kept on skidding in the puddle of milk. The cartons lay on the side of the scene as people rushed over to help them.
That's when store security got involved. They all came over and helped the teens up onto their feet, but it wasn't an easy task. Grantaire's face was red from trying to hold in a laugh, and so was the others'. Everyone was in shock around them, but they were trying not to pee their pants laughing while being helped up by security guards from the supermarket that thought they were injured.
After struggling and even the guards almost falling in the milk, the teens were on their feet and dripping in milk and red-faced. A wet floor sign had been placed near the splattered milk.
"I'm so sorry, I didn't mean to-" Marius attempted to sound sorry for what he did, practically flipping into the air and smashing the milk on the ground, the people all around them thinking it was an accident. The customers were shooed off by the guards, going about their day once more.
One of the guards had shook his head and mumbled something before waving his hand to signal the boys could leave. And with that, they jogged off, slipping and sliding, almost falling with the milk still covering their shoes. Enjolras and the rest were going to be so angry upon hearing this, he hated their antics and pranks they always pulled. Jehan and Joly weren't too thrilled about it either. Jehan thought of it foolish and time-wasting. Joly thought you could catch diseases and sicknesses in some foreign way by doing these things.
Oh boy, was Joly in for a treat when they arrived back covered head to toe in milk and a laughing mess.
