Junior [Junior Comics] #13

Junior doesn't understand geometry so Deena and Goofy offer to help him out. At Deena's house Goofy and Deena fight over how to start and knock over an ink bottle, staining the rug. They try without much luck to remove the stain before Deena's mother sees it. In the end, it turns out it was \"washable ink\" and water would have taken it out just fine from the start.
