Okay, I know we've got Australian Indoor-Rules Quidditch, but this is a game I think we all know the Agents would love to play.
Introducing...
CALVINBALL!

If you don't know what it is, look it up. Now. Until then, try this extract from my fanfiction- I think it pretty much explains it.
“All young boys or tigers are now subject to the Rule of Anachronism, which states that everything is wrong, including this!” Rose yelled, standing on one leg with her arms tied behind her back, and a rubber duckie on her left shoe.
“What does that mean for us?” Hobbes asked, twirling around the Pole of Raining in a spangled pink tutu.
“It means that a shouting match is now engaged between you and Mud,” Rose said, untying her left hand with a spare hedgehog. Calvin, whose name had somehow been demoted to Mud, ran over to one of the two Judgement Waves. Hobbes stood at the other.
“YOU’RE WRONG!” screeched Calvin.
“NO, YOU’RE WRONG!” Hobbes yelled back.
“YOU’RE WRONG!”
“YOU’RE WRONG!”
“ADMIT IT, YOU KNOW NOTHING!”
“NO!”
“NO!”
“NEVER!”
“YOU’RE WRONG!”
“Hobbes has stumbled into the Twilight Zone, and has been set upon by the Vampires of Sparklee!” Calvin directed. His name was now Bin McMud the Second, after an incendiary meeting with Rose’s Fez of Power, which had received an upgrade. Rose’s new name was now Ebony Dark'ness Dementia Raven Way. Hobbes had somehow been able to stay the same, and was now facing the price.
“Ba-ba-ba, ba-ba-banana,” sang Rose, dancing to the beat of the pogo stick, which was hopping by itself.
“Score!” exclaimed Hobbes, kicking the Calvinball through the Pacman Wicket and up Mount Doom. “I’m out of the Twilight Zone, and have scored an extra few Lady Gaga points.”
“Dum-dum-duhhh,” Ebony Dark'ness Dementia Raven Way sang, pointing a Finger of Doom at him, and stomping ominously for extra effect. “Your Gaga points have been subverted into Hannah Montana points, via the evil accordance of Evil Overlord Rule the Eleventeenth.”
“Noooo!” Hobbes sobbed, sinking to the ground. “WHYY???”
As soon as I get Permission, I'm attempting to instate this as an official HQ sport. Until then... thoughts?
