On average how many times do you tell your kids to go to bed?

Most nights my son goes to bed without coaxing. About once a week or so we will get a night where it's, "I have to go potty," "What's that noise," "Can I get some water," "I have to go potty again," and on and on.
The weirdest one I ever got was when he came downstairs and announced his dolphin pillow pet wouldn't stop burping loudly and keeping him up.
