Because this cartoon is only funny if you actually know what a Daruma is...a paraphrased Wikipedia entry will help us all understand.
"Daruma dolls are hollow and round Japanese wish dolls with no arms or legs. Typical colors are red (most common), yellow, green, and white. The doll has a face with a mustache and beard, but its eyes only contain the color white. Using black ink, one fills in a single circular eye while thinking of a wish. Should the wish later come true, the second eye is filled in. It is traditional to fill in the left eye first; the right eye is left blank until the wish is fulfilled."
"Many of the Daruma dolls are male but there is a female daruma doll. It is called "hime daruma" or "princess daruma."
Thus concludes your Japanese culture lesson for the week. There will be a multiple choice test at the end of the semester.
