These are the notes found at the beginning of Sensei no Ojikan 03:

- In Japan, there is a <b>Seasonal Change</b> of Clothes between the two main seasons of school terms. Students have two pairs of uniforms, a summer uniform and a winter uniform. Summer uniforms normally are worn starting on June 1st, and the winter ones around October 1st.

- <b>Collecting on the flesh of your stomach</b> is something of a Japanese proverb. As you probably have expected, it basically means the person will end up lazy and fat with a huge beer belly, give or take. That's why you see "diet" written in the onscreen directly following this line.

- The term <b>Moe</b> can mean two different things, but the more conventional meaning of moe within otakudom is the Japanese anime equivalent to a fetish. More specifically, ‘moe’ means to be attracted to a specific character or its specific partial element and to have a favorable feeling toward it. Some examples in the use of moe are ‘weak girl moe,' and 'glasses moe.' Moe doesn't always point to a sexual object and includes the feeling of cuteness as in the case of Sensei no Ojikan.

- As the name suggests, an <b>I adjective</b> is an adjective that ends in the letter i. Some exmples of I adjectives are ‘ookii’(big), ‘chiisai’(small), and ‘atarashii’(new). This isn’t a golden rule, however, because there are some exceptions such as ‘kirei’(pretty) and ‘yumei’(famous) that aren’t I adjectives.

- The Japanese alphabet is sorted by sound groupings, with the first grouping as the vowels, followed by the ‘ka’, ‘sa’, ’ta’, ‘na’, ‘ha’, ‘ma’, ‘ya’, ‘ra’, and finally the ’wa’ sound groupings. Each grouping is individually sorted in an ‘a i u e o’ order. That’s why, in this episode, Kobayashi has three choices, <b>‘a through u’</b>, instead of the ‘a through c’ that we’re used to.
