A/N: Because where I live it's already AFD, and because I simply couldn't resist. Enjoy!

"Okay, where is he?"

The woman looked ready to kill. Good.

"And hello to you, too, Ms Shaw. You look upset. Anything amiss?" Harold looked the perfect picture of innocence.

"Yeah. I want to know where this overgrown Neanderthal is hiding, so I can put my boot up his sorry a–"

"Hey Shaw. Ugh, is that smell you, or did Bear have another date with the Shih-tzu twins from the beauty salon?" John scrunched up his nose in disgust and coughed a little for good measure. "Really, if I'd known you were coming in straight from your day job, I'd have brought my NBC mask."

"Oh, you think that's funny, CIA boy?" Shaw lunged forward to tackle the tall man, but he easily sidestepped her, so she rammed full tilt into Harold, who was unfortunate enough to be standing half a step behind John. The involuntary couple swayed dangerously and would have gone down hard if not for John's quick reflexes.

As luck would have it, Root chose this very moment to walk in on the awkward group hug. "Ooooh, is this a private party or can anyone join in?"

"Shut up, Root!" Shaw hissed, tore away from the two men and righted herself.

"Why so cranky, Sameen?" Root cooed before crinkling her nose and taking a step back. "Ugh, what is this smell? And since when do you bring your work home?"

"I tell you what this is. Mr Beefcake here apparently found it funny to replace my gun oil with CHANEL BLOODY NO 5!" Shaw lunged for John again, but he caught her in a backward bear hug and lifted her a few inches off the ground.

"Now listen to me. I know you won't believe me, but I had nothing to do with this. Though I have to admit ..."

It was no use. He couldn't keep a straight face, it was just too bloody funny. "Sorry, Shaw, but whoever managed to pull this AFD prank on you deserves a medal!" he snorted.

Shaw went instantly slack, her attempts at hitting John's shins with her high heels forgotten for the moment. "The what?" she asked dumbfounded.

"Happy April Fool's Day, Sameen!" Root sing-songed, sporting a cheeky little smile before vaulting over the wooden bench just in time to avoid Shaw's perfectly aimed tackle.

"Ladies, please!" Harold called after them in slight exasperation as the two chased around the underground platform.

Still laughing, John retrieved the tea he'd brought for Harold and placed it on his desk. "I didn't think you had it in you, Finch," he chuckled.

Harold nonchalantly took the cup, blew a little on the hot liquid and took an appreciative sip. "Mr Reese, I have absolutely no idea what you're talking about ..."
