What does a Cowboy Say?

While getting PJ dressed for the day this morning, he made a request, "G! G!"  At first I thought this meant that he wanted to call G.  But then he started pointing to the box of bibs and bandanas.  I realized, oh you want to look like G.  So I tied a bandana around his neck, to which he was very proud and declared to Daddy that he looked like G.  I told him he also looked like a cowboy.  To which he responded with "Moooo."  All day when anyone saw him, they would comment on how he was a cowboy, and every time he responded with "Mooo."  hahaha
