Two little boys were coloring eggs for Easter.
The older brother says," I'll give you a dollar if you let me bust three of these raw eggs on your head". "
Ok, " said the little brother
So he raps his brother on the head twice breaking two eggs and laughing as the slimy mess ran down his the little guy's face. Then he puts the third egg down and starts walking away.
"You said three, where's the third one? " the smaller boy inquires.
The bigger child, being filled with so much more worldly wisdom replies, " It isn't coming."
"What? Why? " the brother asks
To which the older brother answers," That one would cost me a dollar "
