"Hey...nice asymptote."
Wally rounded on his best friend. "Asymptote? Was that a maths pick-up line? Seriously?"
"My love for you is a monotonically increasing unbounded function." The Boy Wonder continued with a grin. "Being without you is like being a metric space in which exists a Cauchy sequence that does not converge."
"Where do you get things like this?" the speedster asked him, with a pleased sigh.
"The internet." Robin answered. He leaned closer. "I wish i was your problem set, because then I'd be really hard, and you'd be doing me on the desk."
Wally threw his head back and laughed. "That was excellent."
"Thought you'd like those." the smaller boy crossed his arms with a smirk. "Feel free to use them on M'Gann or Artemis or something."
"If I could be any enzyme, I would be DNA helicase so I could unzip your genes."
He turned slowly to stare at the red head. "Good one. Challenge excepted"
"I have more." He grinned. "You're so hot you denature my proteins."
"That one? Not so much." Robin bit back laugh.
"...Okay, how about this: We can do it in the alpha or beta configuration, whichever you prefer."
"Terrible." he nodded.
"Science is harder than maths, alright?"
Robin shrugged. "Not really. What do you say we use my lever to shift your center of mass?"
"Dude, you got all the dirty ones!" Wally slapped his arm. "Okay. Those other guys said that your eyes shine like stars. But can they explain how they shine with equal brightness?"
"We are such nerds." Robin said suddenly, and Wally nodded his agreement. "I'm attracted to you like the Earth is attracted to the Sun - with a large force inversely proportional to the distance squared."
Wally thought for a moment. "According to the second law of thermodynamics, you're supposed to share your hotness with me." He blinked. "We should not know these."
"No, we shouldn't." Robin agreed, but he continued. "Oh, I was gonna give this to supey, but... I think your clothes are made of Kryptonite, we've got to get rid of them immediately."
Wally collapsed on the couch. "Okay, I only have one more."
"-Good, because I'm officially out." Robin fell next to him.
Wally grinned at him, and suddenly Robin noticed how close he was.
"I wish I was RNA, So I could have U."
He could feel Wally's breath mingling with his own. "Something tells me you weren't saving that for M'Gann."
"Nope." He answered simply, before crashing their lips together.

"Artemis? Where are Wally and Robin?" M'Gann asked, offering her a cookie.
"The dorks just spent the last half an hour trading maths and chemistry pick-up lines, and now they're making out on the couch."
M'Gann blinked. "Oh."

I know, I know, they were terrible!
