Itachi and Kisame were walking along a road in the middle of The Land of Sound. Itachi said "Kisame there are two powerful chakra signatures ahead. Be on guard." What they saw was not exactly what they expected.
It was Naruto and Regar but the strange thing was what they were wearing. Both were wearing Akatsuki robes. Naruto was wearing a black wig which spread down to his ankles, the last inch in a ponytail. He was also wearing square glasses with crudely painted Sharingans on the lenses. Regar had a large rubber shark fin tied to his head. There was something that may have been a sword on his back.
The Akatsuki members were staring dumbfounded when Naruto spoke in a loud, dramatic voice. "Look Kisame, impostor Akatsuki!" "You're right Itachi!" said Regar, equally loudly and dramatically. "Let's kill them! I'll activate my Mangekyou Sharingan!" Naruto turned around, threw the glasses behind him and faced them wearing eye patches on both eyes with crayon drawn versions of Itachi's Mangekyous. "Behold the power of Tsukoyomi!"
Naruto took a thin metal sheet and began wiggling it to make a weird noise while saying 'ooooooooooo' in a 'scary voice.
Meanwhile, Regar was facing Kisame. He drew his 'sword' which turned out to be a giant plastic fish. He threw it into the air and made some hand seals yelling "Giant Water Torrent Jutsu!" he then casually took out a water bottle put some in his mouth and sprayed it at a speechless Kisame. He forgot about his 'sword' which landed on his head. He shouted "I see you're a dirty fighter! I'll have to fuse with my sword, Floppyfisha!" there was a poof of smoke and Regar reappeared…wearing a shark costume. 'Rooooooaaaaaaaaaaaaaaaaar!' was all Regar said when he charged wildly at Kisame, flailing his arms as he did.
Back with Naruto, Itachi felt as if he was in Tsukoyomi as Naruto screamed "Who lives in a pineapple under the sea? Absorbent and yellow and porous is he!" for the 98th time. Itachi felt like committing suicide after hearing about someone called 'Spongebob Squarepants' so many times.
Regar was still charging as Kisame stared. Then in a poof of smoke, Regar was above Kisame, 'Floppyfisha' in hand and started smacking Kisame on the head while Naruto was still singing. "Run for it Itachi!" screamed Kisame and the ran off leaving a dust storm behind them.
