Loud and Proud, aka "Kids Say the Weirdest Things"

The Smurfs have been able to visit Smurf 1 in the hospital since Friday, which has been the highlight of their day each time.  It's quite a pain at times because they are either too aggressive or passive when visiting.  Smurf 1 just cannot stand still and wants to push on him and grab his head.  Smurf 2 acts as if Smurf 3 has the plague and is tentative about going near him.  However, after we have left she talks about him as if she was taking care of him and had a great time.   So on the first day they got to visit, both were understandably excited.  They were asking a bunch of questions, looking at stuff, saying how cute Smurf 3 was, etc.  Well, his diaper needed to be changed, and surprisingly Smurf 1 wanted to watch (Smurf 2 has backed away several steps because she's just timid in this situation).  When his diaper comes off, Smurf 1 notices that Smurf 3 has an inflated belly button.  He has a small hernia that makes his belly button inflate, but it's supposed to correct itself.  Anyway, he looks at it and declares (quite loudly):

"Look! He has a belly penis!"

 A couple of the nurses tried their hardest not to laugh, but it couldn't be helped.  I laughed so hard I started coughing.  It's not a misspoken word or phrase, but i'm counting it as one.
