To get back to present time:
Suck on a juniper berry. Remember the time you're from. Then walk in front of a person so they can see you. Then yell, "FRIED CHICKEN!" This will disrupt the time flow thereby sending you home.
get a gummi bear, nut, pickle and potato mash them all together then eat them and jump of a cliff singing "can't get enough of that sugar crisp".
