Corrected entry: In one of the first scenes, when all the Klumps are going to dinner, Sherman says, Klump, party of SIX. But lets count. There's Sherman, Mom, Dad, Grandma, that fat little kid, that bald guy with the mustache, Grandma's old boyfriend, and Janet Jackson, that's EIGHT. For a University Professor, he's not very good at counting.
Correction: It's not Sherman's mother who says that. She says yes, and we're hungry after Sherman says his line.
Correction: Grandma and her old boyfriend arrive late.
You will also notice that it's Sherman's mother that says "Klump, party of six", not Sherman.
