Bedtime is by far the biggest stressor of my day everyday. 
On one particular night, I finally had all the kids tucked in and was working on homework in my room, I heard some talking and some giggles coming from the Little's room. Pretty soon Dayton approached my bedroom door and in a giggly voice said: Mom I hafta go potty
Me: No you don't
He ran back to his room and announced "Dang it didn't wurk"
