Conversation with Ben

Here is the conversation I had with Ben this afternoon while he was sitting on my lap...

Ben: "Whatcha doin, mom?"
Mom: "Just sitting here, Ben. What are YOU doing?"
Ben: Pausing for a minute, then answering with a smile - "Eating poop."

Where does he come up with this stuff? I wonder if he is sneaking out of bed at night to catch Leno and Letterman. :)
