We sat them down with Kasen, telling them that we wanted a more recent photo of the three of them, and then said, "1, 2, 3... Carrie's pregnant!" waited a beat and took the picture.
This is the result:
Mom's saying, "Wha...?" and Dad's expression needs no explanation.
They were shocked, then didn't believe us, then started crying. It was so awesome! I also got it all on video without them knowing ;)
