Sliced it off.

My son knocked on the bathroom door frantically saying he had to go potty. I opened the door to let him in and he wasn't there. I found him playing in his room.

Me: Bathrooms free.

Son: I don't have to go.

Me: Did you go in your pants?

Son: (almost hurt) no.

Me: But you knocked saying you had to go.

Son: i had to go potty.  But i accidentally sliced it off.

Me. Oh ok. (I started walking away.) Sliced what off?

Son. It.

Me. Whats it? What did you slice off.

Son. I had to go potty and it came out and i sliced off the poop.

Me: With what?

Son: (shrugging his shoulders.) I dont know.

Me: OK? Where is it?

Son: In my pants
