I heard Jack grunting from the bathroom. Then came his sighs and then a small voice squeaked, "oooouuuch!".
I peeked my head around to corner to see what was going on and found him with his pants still around his ankles.
Me: You alright in there?
Jack: Yeah, (sniff) I was just going potty.
Me (peeking my head in the toilet): Whoa! That is a big poop, Jack.
Jack: Yeah, it was pretty hard to push it out.
Jack: It was hard but I just used my super-pusher to push it out.
Me: Oh, okay.
Jack (turning around and bending over): Now can you wipe my bottom?
