Things that make priests roll their eyes

I could so easily see my kids doing something like this:

Well my 2 youngest are making First Communion and we were going over the ceremony with them. When we got to the place where the priest does the Holy water sprinkling they both jumped up and (In a deep low voice) began intoning "IT BURNS, IT BURNS.........

I'm figguring the entire family will be excomunicated the day after their communion.
