Run up to people and try to convince them that you are from the future and if they do not come with you then they're life is at severe risk. Throw in some crazy outfits and "evil" people from the future chasing you. It wouldn't hurt to get some fuckin explosions to make it seen legit. Now, if you've got them semi convinced, tell them they must come to the future with you and get into a time machine with them and then when your all in there it will be shaking and what not to give it the full effect. During this process, you will get all these people who like like theyre from the future outside so when they get out it seems believable. That's all I got. You can do some crazy ending if you'd like.
