So here is my own interpretation of what I saw in common between the Grinch and Obama:
"The Grinch had been caught by this little Who daughter
Who'd got out of bed for a cup of cold water.
She stared at the Grinch and said, "Santy Claus, why,
"Why are you taking our Christmas tree? WHY?"
But, you know, that old Grinch was so smart and so slick
He thought up a lie, and he thought it up quick!
"Why, my sweet little tot," the fake Santy Claus lied,
"There's a light on this tree that won't light on one side.
"So I'm taking it home to my workshop, my dear.
"I'll fix it up there. Then I'll bring it back here."
And his fib fooled the child. Then he patted her head
And he got her a drink and he sent her to bed.
And when Cindy-Lou-Who went to bed with her cup,
HE went to the chimney and stuffed the tree up!
Then the last thing he took
Was the log for their fire.
Then he went up the chimney himself, the old liar.
On their walls he left nothing but hooks, and some wire."
