AN: The song is 'Baby It's Cold Outside' minus the creepy date rape implications. Sam is stuck at Artie's due to a snowstorm.
With his parents gone on a business trip and his little sister sleeping over at a friend's house, Artie felt that it was perfectly logical for him to have Sam over. They could finally spend some time together uninterrupted and didn't have to worry about anyone walking in on them. While Sam had been there, it had started snowing and had continued throughout the afternoon and into the night. They hadn't taken much notice of it at first but as it got later, they noticed how much snow had piled up throughout the day.
"You can't drive in that," Artie said as they peered out the window. "It's way too dangerous and I doubt the plows will be out anytime soon."
"I have to try," Sam said. "My parents will be worried if I'm not home."
"Tell them that you're going to sleep over here. Then they'll know that you're safe."
"I'm pretty sure they won't like the fact that we'd be here by ourselves."
"Why? We can take care of…oh. Well…just mention that we have a guest room or something."
"You'd stick me in a guest room?"
"Of course not. But they don't need to know that."
"I don't know. I bet I could make it."
"Sam, take it from me. You don't want to drive in crappy winter weather. I know what can happen."
"Are you trying to guilt me into staying here?"
"…maybe a little bit."
"But if it's this bad out, nobody else will be driving and I'll have the roads to myself and can drive as slow as possible."
"There will still be ice and snow. They're not going anywhere anytime soon."
"Look, it's not that I don't want to stay here, but if we have a 'sleepover' I'm pretty sure our parents will figure things out and we might never be trusted again."
"They can't blame us for this. It's not like we did this on purpose. They wouldn't want you getting hurt or worse by trying to drive home."
"You're going to knock me out or drug me in order to get me to stay here, aren't you?"
"I'm hoping it doesn't come to that. I'm actually a little hurt that you don't want to take advantage of this opportunity."
"Of course I do. I just…"
"…."
"Screw it. I'll call my parents."
"I'm sure they'll understand completely."
"You don't have to sound so smug. I blame you completely."
"What do you mean?"
"You were giving me that look. It…suggested things."
"I take it you are open to suggestions then?"
"…oh shut up."
Sam's parents weren't jumping for joy that their son was sleeping over at his boyfriend's house unsupervised, but they didn't want him to risk driving home in the storm and Sam promised that he would sleep in the Abrams' guest room. Although what they didn't know wouldn't hurt them.
