Okay... just looked through the Curious George Books in the house (all 7 of them). The "thing" on the Man with the Yellow Hat's desk is only in the first book. Although his desk is seen in three of the other books, the "thing" is not on it. My guess as to what it is? It looks like one of those useless yet amusing things that men sometimes have on their desks. They sell big around Father's Day when kids want ot get their dad's something, but don't know what to get them. You know... something that you push the end of and it swings back and forth and gives you something to stare and and do while you are on the phone, or whatever...
