I'll start: (I originally posted this on the "strange okiya hint" thread and I ran out of ideas)
This is all about Okiya's cooking skills.
Okiya: Breakfast is served!
Gin: What the hell, Okiya? Where's my steak?
Okiya: How can I buy meat if all the BO's money is used on funding the APTX project?
Gin: *points gun at Okiya* I said, where's my steak?
Okiya: Dammit Gin! You can cook your own steak! I'm getting the hell out of here! *walks out*
Gin: Hey, I'm just kidding, man! Come back here!
Vodka: *comes out of nowhere* What's the fuss about, Aniki?
Gin: Our cook is gone.
Vodka: WTF? Who's gonna cook now?
Gin: *evil grin* We're going out.
(after a while)
Conan: Ran-neechan, I'm home! *sees Gin and Vodka* What the?
Ran: Conan-kun! Meet our new boarders! They're going to clean our house everyday in exchange for food!
Gin: *looks at Conan* Do I know you from somewhere?
Conan: Uhhh,, No?
To be continued...or you can continue it

(special thanks to Aluecard, it's his idea to write an Okiya fanfic)
