Pee again

My youngest, who turned two about 3mos ago, still occasionally needs help getting her pants down in the restroom, so I frequently just go with her when she needs to go. Yesterday as I turned on the light in the room, it was obvious that one of my older boys had not only not lifted the seat, he'd not aimed well either, and there was quite a bit of pee all over the seat. Before I could holler at the boys to come clean it up, the 2-year-old heaved a big sigh and said, "Oh dang. They did it AGAIN."
