Hide the phone

My little guy loves to crawl around and get into things he shouldn't .  I think that all kids do.  Well he got my cell phone like always., so I said give that phone to mommy.  Usually he will smile and hand it over.  Well today, he put the phone under his butt and sat down on it.  He was so proud of himself.  I could not stop laughing.  he would not give it to me until I picked him up.
