One day, Deidara had finally had enough.

"Tobi." he barked. Tobi came running to him.

"YEEEEEEEEES, Deidara-Sempai?" he squealed.

"Why, un," Deidara asked. "Are you a good boy, Tobi?"

Tobi sat. He stared. He stroked his nonexistent goatee. He stood on his head (1). He consulted Wikipedia.

"... ... ...Tobi doesn't know why Tobi is a good boy!" Tobi gasped in wonderment.

Deidara snickered. "Then...is it, un, possible that Tobi, un, is a bad boy??"

Well, THAT totally set Tobi off.

Deidara watched in horror as Tobi underwent a terrifying transformation.

"TOBI IS A BAD, BAD, BOY!!" The Tobi-monster roared.

"N...n..o...no, no, no, un! Tobi is a good, un, boy, Tobi is a good boy, un!" Deidara shrieked in horror.

There was an audible popping sound as the Tobi-monster turned back into Tobi.

"Tobi is a good boy, right, Deidara-sempai?" Tobi asked sweetly.

"Y...yuh...yes, un," Deidara whimpered.
