Great Outdoors scene?

[Jarad]

me and my friend were discussing the movie, The Great Outdoors starring jon candy and dan akroyd, and he said a funny part is when the red headed twins were sitting on the dock and the mother says, "girls you dont want to go swimming" and a big fish jumps out of the water. I cant seem to remember this part so i said it doesnt happen in that mnovie. Can someone clarify if it does happen, and if it doesnt, what movie does it happen in, thank you
