So I uploaded pencil versions of these two parts on Deviantart in 2007. But I combined them recently and added color in Artrage and thought to reupload it here.

Here is the old description if you like to read descriptions:

Part 1: This is a idea I came up with when my friend told me this blinking game.
It's a game with two people stare at each other's eye and the person that blinks first lose. naruto and sasuke both don't want to lose to the other. I don't know what their eyes feel like without blinking for 4 hours, and I don't want to know!

Part 2: I thought of this when my friend always talk about that she's taller than me by 1 or 2cm.
well, all my friends are taller. I hope I'll catch up someday!

Here is the old pencil sketch in two parts done on looseleaf paper if you want to check that out
