I was browsing a few of the Naruto books I have and I stopped at a picture of the Yondaime.I took out volume 30 and flipped through it and found a picture of Naruto,the same position,the same upper-lip curve.
Then I remebered back.....Naruto was learning some of the Yondaime's techniques.
Think about it to....Narutos the only orphan in the village,He has no idea about his parents,His parents "died at birth" and was the only person to summon Gama Buma after the 4th.Also before the Gama summoning Jiraya said,"Forgive Yondaime,Ill have to teach him the hard way."
On top of all of that Tsunade thought the foruth was a rude and annoying kid.
Does that ring a bell about Naruto's personality.
I'm really puzzed if Naruto is his kid or not.
Please if you can give me any more details,please post them here at this journal.
