Adam: One little change has a ripple effect and it effects everything else. Like a butterfly floats its wings and Tokyo explodes or there's a tsunami, in like, you know, somewhere.
Jacob: Yes exactly. You step on the bug and the fucking internet is never invented.
Lou: Oh then you'll have to talk to girls with your mouth.
Jacob: Yeah. No. I was more concerned about bigger consequences like not being born.
Lou: Yeah. No. I don't care about that.
Trivia: When the foursome ski down the mountain and are looking around at the oddly dressed people, someone behind John Cusack says, "Hey Lane, you owe me two dollars". This was a nudge to John Cusack, who played Lane Meyers in "Better Off Dead" and was pursued in the snow by a crazed paper boy shouting "Two dollars!"
More questions & answers from Hot Tub Time Machine
Chosen answer: The James Bond film "A View To A Kill" came out the year before in 1985. In the film, Bond's snowscooter is blown up by the Soviets, so he takes a wrecked ski from it and improvises it into a snowboard. Snowboards existed at the time, however, it wasn't until that film that their existence became well known. One year later in 1986, they'd still be very rare, but it's likely that his wasn't the first that the ski patrol had seen.
