Why.....

....Because I was helping you momma

In case you can't tell what is in the washer here is a picture of the inside of the washer.  She took all the shoes off the little shelf in the laundry room and put them in the washer

....Because Emmett thought it was fun

Emmett thought it was so funny to be carried in the laundry basket

....Because its a Giant Candy Bar

Both of them walked up to the display and started acting like they were eating it.

....Because it looked like a fun place to put all the balls

I found all this inside of the sub speaker next to the tv cabinet.  Emmett had put all these balls in the tub that is on the front.
