When Billy has two black eyes and is talking with his dad...the shape of his shiner on his right eye changes. At first...his black eye is right around his eye...and then the bruise is from his temple to halfway down his cheekbone.
On the first Christmas...a little boy guesses there are 2459 jelly beans in the jar...but Joey wins with a guess of 2456 jelly beans. On the last Christmas...Billy adds 3 jelly beans to the jar. The little boy wins with a guess of 2456...the same that Joey won with on the first Christmas.
