And before anyone complains about stereotypes in that episode, the main reason my wife thought it was hysterical was because earlier that day, two of the old farts at her company had actually commented to her “we heard your husband’s American. Wow. Big penis, huh?”

Boy, those Japanese really have our number, don’t they?
