If we're going to start listing irritating kids in the movies (and not just those seated with us), I nominate Eric Shea, in The Poopside-Down Adventure. Danged brat, Shelley Winters must have been gagging every time she had to say he was "such a dear, sweet boy." I can hear her now: "Is it time for my heart attack yet? Oh, thank GAWD! I'm outta here!"
