Jack listened intently as his wife Maddie turned the dials on a new speaker system. It was installed in Danny's room and Lyndsay's room; they just had to make sure it worked.
He motioned for her to stop when he heard Lyndsay's voice come over the speakers.
"Come on, Danny. Just let me try."
"NO," they heard Danny grumble.
"Why not?"
"Because I don't want to."
"That's it?"
"If someone catches us, it'll be awkward and we'll probably get in trouble."
"Danny, you say catch like what we're doing is wrong."
"Well, it can't be good for my health."
"Wuss."
"FINE."
They heard Lyndsay chuckle. "All right, grab a pillow and put it on the floor."
"Why?"
"Because if you don't, it'll hurt when you get up."
"Won't it hurt anyway?"
"Not if I do it right."
The Fentons looked at each other. Were they doing what they thought they were doing?
Danny sighed. "Fine."
They heard footsteps. "All right Danny, lie down on your stomach and put your head on the pillow."
They heard a clunk as Danny lay down.
"Wow, no comment?"
"I've learned not to question you."
"It's about time," they heard Lyndsay mutter.
Maddie groaned. They were.
"Now just relax."
"Okay."
They heard a pop. "See?" Lyndsay asked.
"You were right, I guess."
"You guess?"
"Yeah. You know, this actually feels kinda good."
"Told ya."
"Shut up."
Another pop came through the speakers. "Ow ow ow," Danny whimpered. "Too low."
Jack and Maddie raced up two flights of stairs and into Danny's room.
Both teens turned to face them, Lyndsay standing on Danny's back.
She nimbly stepped off and walked towards them. "Hi Mr. and Mrs. Fenton!"
Her tone was so cheerful and innocent that they couldn't help but laugh.
"Did I miss something?" Danny asked as he got up and walked over.
Jack chuckled. "Nothing you'd get. An inside joke, as you would say."
They left the room, leaving Danny and Lyndsay confused, bewildered, and a little bit concerned.
"And this," Maddie said while gesturing backward. "Is why we can't spy on those two."
"Agreed," Jack said. "How about some fudge?"
