Perilous Time Travel
"Dammit, Sam! What did you go and touch it for?"
"I didn't touch it!"
"Well, how do you explain this, then?"
"I uh, can't."
"You touched it!"
"I was only wiping off some dirt!"
"What the hell would you go and do that for?"
"Oh, I don't know, Dean, maybe to read the runes on it?"
"Not-touching comes before rune-reading!"
"How did you even know not to touch it?"
"Because it said 'DO NOT TOUCH' on it. But it was easy to miss, I suppose. It's not like you have eyes or anything."
"Where? I read almost half of those runes and--"
"Not the runes you dipwad, it was spray-painted across the top in neon pink."
"Graffiti? I'm supposed to pay attention to graffiti any punk teenager could have put there?"
"Well, yeah, when ignoring it lands us in the middle of nowhere!"
"Because I knew exactly what was going to happen. When I wiped off that bit of dirt, I somehow knew that we were going to end up up to our ankles in mud with no idea where we are!"
"Well, the freakin' foot-high, bright pink 'DO NOT TOUCH' might've been a clue that something bad would happen if you touched it."
"Okay! Okay, I fucked up, but arguing isn't going to do anything. We need to work out how to get back."
"We need to work out where we are."
"Do you think if I touched it again...?"
"Christ, Sam, no!"
"Dean, get off me. I wasn't actually going to touch it again, I was just asking!"
"Yeah, well, don't. Hey, is that a guy over there? Behind that tree? Hey! Hey you! Guy! You behind the tree! Can you tell us-- Whoa, okay, so wherever we are, they don't speak English."
"And they wear a lot of fur."
"I didn't realise you were into animal rights."
"No, I don't mean that, I mean he was only wearing animals skins. Have you ever seen clothes like that?"
"Not outside of a museum."
"'Exactly'? Exactly what?"
"I think we're in the past, Dean."
"...You have got to be kidding me."
"No, Dean, think about it--"
"Maybe it addled our brains and we only think we're wherever we are."
"Or we might actually be wherever we are."
"Either way, we need--"
"Shh, listen. You hear that?"
"Yeah, sounds like... an elephant? It's too cold for elephants isn't it?"
"Dean, don't wander off. I think we should stick by the rock."
"Yeah, yeah. Just doing some..."
"Dean? What is it?"
"Run, Sam! Run! Go! Touch the rock again! Shit!"
"Fuck, Sam. That was a woolly mammoth! A woolly fucking mammoth!"
"I told you not to wander off!"
"Shut it. We're back safe, aren't we?"
"Well, it looks like we are, but until we know the date..."
"There aren't any mammoths around. I'm counting that as a win."
"What were you thinking going looking for the mammoth, you freak?"
"Oh whatever, I'm the stupid one? Mr. I'm-going-to-wipe-off-some-dirt-and-transport-us-back-in-fucking-time."
"We've been through this."
"Yeah, and when we get back to the car? I'm going to cut your hands off so we don't have to go through it again."
Wasn't that fun?
