Sadness looked between the glass in front of her and Joy's maniac grin.
"So you want me to what?"
Joy feigned an exasperated sigh, saying "We both drink the water, keep it in our mouths, and then try to make the other laugh. The one who spits out the water is the loser."
Sadness sat silently for a few more seconds before she said "Alright, I'll do it. But full disclosure, this is the worst date night idea you've ever had."
"Noted." Joy replied before downing the contents of her glass, puffing up her cheeks. Turning back to face Sadness, she almost lost immediately. Sadness's face with puffed out cheeks nearly made her heart pop like a balloon. But she regained control of herself and tried to think of ways to make the very embodiment of unhappiness laugh.
Sadness sat in thought for a while before it hit her. She's practically won already. She's playing against JOY. The woman laughs when wind blows leaves off of trees. But it couldn't just be anything that let her win. It had to be big. If Sadness was going to make Joy laugh, it was going to be special or so help her God she would spit all this water down her own sweater. Interrupted from her thoughts, she focused on Joy dancing around the room doing various animal impressions. 'Cute' Sadness thought 'but not even close babe'. She made sure to convey this in the look she gave Joy. Pursing her lips, Joy say back down again, tapping her fingers while she thought. Fear did tapping like that sometimes. Fear! 'Got it' Sadness thought. Catching Joy's eyes with her own, she brought the taller emotion back to reality. Raising her hand in a lazy gesture, she concentrated.

Joy never stood a chance. As soon as Fear came screeching out of his room soaked to the bone with rainwater, it was all over. She snorted, desperate to last a few more seconds, but eventually she caved, spitting water all over the table, Sadness, and herself as she laughed like a madwoman. Sadness, glad to have won, spat her water at Joy for revenge. "Sorry Fear." she called over her back. "I needed to make Joy laugh."
"You could have chosen literally ANYTHING. And you went with drenching me with a rain cloud?"
"I know. I'm sorry. But look at how well it worked."
Sure enough, Joy was laying on the floor in the fetal position still laughing, seemingly uncaring that she was laying in the puddle of water she and Sadness had created.
Fear looked down at the yellow emotion, sighing and saying "Yeah. Ok that did work really well."
"EVERYONE GET THE F*** TO BED!" Anger's voice raged out of his room.
"He really loves those new swears." Fear muttered before shaking himself off and heading back to change.
"I'll make this up to you!" Sadness called after him, helping Joy up and leading her to their room.
The next day she let Fear into her room for ten minutes with freedom to do what he chose. After the ten minutes, she re-entered to find everything nailed to the ceiling.
