Fred and Barney exchanged blank looks. Fred scratched his head, attempting to piece together the alien's words. "Uh, Gazoo, we haven't really done advanced math like... whatever that was."
Gazoo sighed, rubbing his temples. "Let's see, how do I simplify the expression...? Oh, never mind. It's beyond you dum-dums. Just trust me."
Fred frowned at the return of the insult but decided to let it slide. "How long are you going to need the hiding space?"
Gazoo shrugged nonchalantly, hovering beside the closed garage door. "Who knows? Could be a few days, could be a few centuries."
"C...Centuries?" Barney stammered, turning pale.
Gazoo waved off his panic. "Oh, don't get your tights in a twist. It was merely a figure of speech. Anyway, as long as it's here, I owe you two primitives some favors."
"Favors?" Fred echoed, interest piqued.
"Yes, favors," Gazoo confirmed, "but we'll have to be careful about that. Paying back favors can be a tricky business, especially with you two involved. Let's just focus on the task at hand, shall we?" He floated towards the tree, leaving the boys in a whirlwind of questions and disbelief.
