Sam holds a Geography text book entitled "The World and It's People," with the incorrect contraction of "it is" instead of the possessive "its."
When Coach starts teaching Sam about the world's nations from a geography textbook, he starts with Albania. But the nation that comes first alphabetically is Afghanistan.
Sam only dials six digits on the telephone when calling his teacher.
In Sam's office, while Sam is asking Diane not to tell anyone that he's back in school the shadow of the boom mic can be seen moving along the wall behind Sam's left shoulder.
Diane and Sam (but Diane first) both mispronounce "Pierre." When referring to the capital of South Dakota, the city is pronounced "peer," not "pee-err."
