"This is a bad idea," said Sam through clenched teeth. He kept his eyes fixed on the ramp at his feet, away from the twisted metal monstrosity that towered above them.
"Don't be such a baby," said Gabriel. He tugged Sam along like an eager dog on a leash. They moved along with the herd to the metal train of roller coaster cars. Sam saw with a sinking feeling in the pit of his stomach that the very front car was as yet unoccupied, and that Gabriel was leading him straight to it.
"You've gotta be kidding me."
"Sit," Gabriel ordered.
Sam lowered himself into the plastic seat. He had to slump down and fold his legs almost double and tilt them diagonally to fit. Gabriel watched his contortions, failing to suppress silent fits of giggles that didn't stop until the ride attendant came to lower their shoulder restraints.
Sam fell completely silent and his (extremely attractive) face blanched considerably.
"Relax!" cried Gabriel. "Sam Winchester, scourge of nightmares and monsters, terrified of a carnival ride!"
"These things are not safe," Sam said, still with his teeth clenched so tight Gabriel feared his jaw would break. As he spoke, the train clanked and started up the long first hill, and he clamped his fists around the handholds, turning his knuckles completely white.
"I hate you," Sam muttered over the deafening sounds of the motor. "I hate you, I hate you, I hate you, I hate you."
Laughing, Gabriel reached over and grabbed Sam's hand. Sam squeezed back so hard Gabriel felt his knuckles pop, but he made no move to free himself.
They had reached the top of the first hill. From here they could see the entirety of the amusement park, and over the highway to the Rocky Mountains.
"Holy crap."
The train eased over the crest and shot downwards. Gabriel's left ear was suddenly assaulted by perhaps the strangest noise he had ever heard. He never thought he would hear a Winchester scream like a little girl.
Sam's hand released Gabriel's, but it was only a brief respite as he discovered only a second later where it had gone. A forceful hand ran repeatedly down the left side of his face in time with Sam's screams. The train hit the first dip, and Sam's voice rose an octave in pitch, but this only made Gabriel laugh harder, resulting in one of Sam's fingers catching in his mouth. Gabriel spluttered as Sam's hand tightened around a hank of his hair.
A minute and a half of hilarious agony later, Sam and Gabriel climbed out the other side of the roller coaster, Sam with a firm clamped on Gabriel's shoulder his legs were shaking so badly.
"You…" began Sam in a trembling voice.
Gabriel raised his eyebrows expectantly.
"…suck."
As they emerged from the exit gate, they spotted Dean leading a similarly pale and unsteady-looking Cas away from the river log ride.
