My son - then 2 1/2 was still potty training. He loved big words. He had spent time with grandma. Grandma taught him to use the big boy word when he went to the bathroom - ok - 'bowel movement' So we were sitting in the living room and he was in the half bath with the door open - he was a big boy so he wanted to go alone... ok... Well, we heard BABOOM!!! some grunting and BABOOM!!! and more grunting and BABOOM!!!! so when he came out I inocently asked him what he was doing in there and he proudly said, "I was making some BOMB MOVEMENTS!!!"
