L.,
I am not sure that these 2 events are related. To be honest, he is acting like a 4 year old boy. He wants to be funny because he wants others to like him. All of my kids have the same tendancies. The 6 year old is an audience as he is also an audience for the 6 year old. I would just make sure that you are consistant with the idea that school time is learning, sitting, listening time, and make sure that he has plenty of time (and an audience) to goof off. Maybe you can make a chart, that every day he gets a good report he gets a sticker, stamp, or check, and after 5 days (and later 7 and later 10) he gets a small treat, like a whole dollar to spend however he wants at the dollar store.
I would also reccomend that you read a book on boys and education. Dr. Dobson's "Bringing Up Boys" was a great one for me. I have to say that I had my eyes opened.
Good luck - and enjoy! Pretty soon he won't want anyone's attention!
