Explanation:

Irregular plural nouns do not follow the standard rules of adding "-s" or "-es". Instead, they have unique forms that must be memorized. For example:
- "Foot" becomes "feet".
- "Goose" becomes "geese".
- "Man" becomes "men".
- Some nouns remain the same in both singular and plural forms, such as "deer" and "sheep".

By understanding these irregularities, you can correctly fill in the blanks with the appropriate plural forms.

Final Answer:
\boxed{feet, geese, men, people, fish, tomatoes, mice, children, deer, families, teeth, sheep, monkeys, dice, pianos, moose, oxen, thieves, videos, women}
