The Letter U (or Homophone Fun)

KinderCare has a display near its entrance with ABC blocks, and the letters D, E, F, and G affixed to the table on which the blocks are sitting. Joe likes to point out letters on his way in and out. This morning, the whole family went to drop Joe off (Julie and Clara were then continuing on to Lake Calhoun for their daily walk; early today) and Julie walked in with Joe. We stopped briefly at the blocks and then continued in at which point Joe ran to the desk to point out more letters in the "Sign up today" posted across its front. He was stymied by the U and asked what it was. When Julie replied that it was a U, Joe promptly pointed to himself and said "You right here!"
