Pot. Kettle. Black.

Today's bumper sticker – and Seto's quip about multi-tasking – is brought to you by Lady Grey.

'Pissing Off the Entire Planet, One Person At A Time'

"I gather they're starting with you, big brother?" Mokuba smirked.

Seto glared at his brother. "Look who's talking," he snapped.

Mokuba just grinned cheekily.

"Any idea who this one's from?" Joey asked.

Examining the envelope the newest link of the insult chain had come in, Serenity said, "No clue. There's no return address, and the postmark is from right here in Domino."

"That narrows it down to…everyone," Mokuba said brightly.

Seto scowled down at the abhorrence lying so innocently on his desk – otherwise known as a bumper sticker. "This isn't fair."

Raising one blond eyebrow, Joey said, "What, you don't think it's at all appropriate for you?"

"Hn." Seto glowered at his koi. "Pot. Kettle. Black," he growled.

Mokuba and Serenity giggled.

Joey rolled his eyes.

Seto smirked. "See? I'm great at multi-tasking. I can talk and piss you off at the same time."

Joey growled under his breath. Reigning himself in, he heaved a sigh. "What isn't fair, Seto?" he asked, using the brunet's given name so Seto would know that he meant business.

Giving in, Seto turned his attention from infuriating his boyfriend back to the matter at hand. "I've been hit twice; you, once; Serenity, also once," Seto listed. "Mokuba hasn't been hit yet, but I'm extremely thankful for that."

"So are we," Mokuba and Serenity chimed in.

Shooting them a quelling glare, Seto said, "To continue… Yami was the one who started this whole thing, and he's only been hit once since its inception."

"Yeah, so?" Joey interrupted impatiently.

Seto shot the blond a Dragon Death Glare ™. "Yugi, however, has not been hit once," he revealed. "You and I together have been hit three times; Yami and Yugi are way behind, don't you think?"

"Well, if you look at it that way..." Mokuba started.

"Mokuba and I are also behind," Serenity finished.

Seto started. Joey smirked. The CEO chuckled ruefully.

"Pot. Kettle. Black," they chorused.
