Jack: Ehh, I suck the house into a parallel dimension one time, and you just can't let it go, can ya?

Parallel Worlds
"Daddy?" Jazz asked, holding onto her father's leg. "Where are we?" The older man looked around as creatures that looked like a mix between a cat and a bird flew by, hissing at them.
"I don't know, Jazzypants," Jack said, holding his daughter tight. "It must have been the Fenton Nightmare Machine. It sucks ghosts into their worst nightmare… but I guess it works on humans as well. Your mother will not know about this, understood?" Jazz nodded.
"Yes, Daddy. Can we go home, now?" she asked. Jack looked downfallen.
"I don't know how, Princess," Jack said. "We're just lucky you're mother's not going to be home with Danny for the next few hours. It gives us some time to get out of here." Suddenly the world around them faded away and their lab appeared in its place. Jack grinned innocently at his wife, who was glaring at him.
"Jack Fenton, what in the world were you thinking?" Maddie screamed. "Jazz is only five years old! You know for a fact that too much exposure to ectoplasm might hurt her!"
"But Mads…" Jack said, defeated. Maddie was holding their three-year-old son in her arms. They had gone to the doctor to check out his ear infection, and when she'd gotten back their latest invention was humming and Jack and Jazz were nowhere to be seen.
"No buts, Jack. Jazz could have gotten seriously hurt. She could have… I don't even want to think about what could have happened."
"At least we know it works," Jack said. Maddie narrowed her eyes.
"But it's only supposed to work on ghosts, not humans!" she said sternly. She put Danny on the floor and the blue-eyed boy stumbled up the stairs to the kitchen. "Jazz, go upstairs with your brother." The girl obeyed her mother's orders.
"Maddie…" Jack started. Maddie sighed.
"Jack, we've been over this before," she said. "I am the only one who will test the inventions. Now go up and get some cookies before the kids eat them all." Jack grinned and bounded up the stairs, screaming "COOKIES!" all the way to the kitchen. Maddie smiled and followed him upstairs.
