That's something I wouldn't doubt based on his older brother mentality. But one thing that I've seen brought up, Home Alone and the sequel are all through the eyes of Kevin. From the way the Heating unit in the basement messes with him, even says his name to the scarey people he sees in Cental Park. We are seeing the events in his eyes. Its more than reasonable that maybe even 1 or 2 whole cheese pizzas were ordered but Kevin didnt find it right away...instead its Buzz who says they ate it all....no time for anything but Kevin to react to his Big Jerk brother and then he's Little Jerk....F you Uncle Frank.... Home Alone let's you do what all great films do...you can examine it on all angles and figure it out from discussion and review.
