http://www.southknoxbubba.net/skblog/George W. Bush is out jogging one morning, and notices a little boy on the corner with a box. Curious, he runs over to the child and says, "What's in the box kid?"
The little boy says, "Kittens, they're brand new kittens."
George W. laughs and says, "What kind of kittens are they?"
"Republicans," the child says.
"Oh that's cute," George W. says and he runs off.
A couple of days later George is running with his buddy Dick Cheney and he spies the same boy with his box just ahead. George W. says to Dick, "You gotta check this out" and they both jog over to the boy with the box. George W. says, "Look in the box, Dick, isn't that cute? Look at those little kittens. Hey kid tell my friend Dick what kind of kittens they are."
The boy replies, "They're Democrats."
"Whoa!", George W. says, "I came by here the other day and you said they were Republicans. What's up?"
"Well," the kid says, "Their eyes are open now"
