Danny was still at work when Sean opened the door to welcome his cousin Joe
"Hey, come on in! Today's gonna be awesome!"
The newest-yet-oldest cousin in front of him smiled
"Oh yeah? This have anything to do with the spontaneous pranks between Uncle Danny, you, me and Jack?"
Sean grinned
"Exactly. Let's prepare him a ... proper welcome home."
Joe chuckled just as mischievously, almost an evil cackle
"Not much is more important than good old-fashioned hospitality, after all."
Sean fist-bumped him
"Finally someone gets me!"
Trading ideas and curating their pranks to perfection, they soon boobytrapped the house so opening the door would set off a tripwire and pelt Danny with water-filled balloons. Easy cleanup, not too much damage. Amateurish, sure, but it was the best they could do in short notice. Soon enough, everything was set and they settled with a cop show on TV waiting to see their handiwork unfold. Their gratification would come an hour later, as the door swung open and Danny spoke
"Hey, Ki-"
He was effectively cut off by a brigade of 50 or so balloons of icy cold water, and his laughter bounced around the walls of the house, as he doubled over in hysterics, the boys soon following. Composing himself, Danny went to shower. Sean turned to Joe after they high-fived
"You know revenge will be brutal, right?"
Joe nodded
"Sleep with one eye open. I know I am."
Instead, the two had a different idea, and ended up eating snacks and binging horror movies all night. Icing on the cake for Danny was that between the sleep deprivation and scary movies, they were so jumpy the next day that he did not even have to work hard to scare them.
