Side note, at 3:38, when the question is asked which population size could be more affected by genetic drift, this is a wonderful analogy to how grades fluctuate more wildly early in the semester with few assignments (i.e., "small population"), but later in the semester, when there are far more assignments entered, the grade is much more stable, less likely to be impacted by any one assignment (i.e., "large population"). It helps reduce the number of students rushing to me at the end of the semester asking for some epic grade improvement. :-)
