Billy Madison is a 1995 comedy starring Adam Sandler as a wealthy heir who must repeat every school grade to inherit his father's hotel business. The film became a staple of nineties comedy, with its classroom scenes and over-the-top school humour quoted long after its release. Short clips like this one circulate online because they are instantly recognisable to fans and easy to drop into unrelated videos. The chlorophyll moment works as shorthand for school, science class and forced learning, which keeps it useful for memes, reaction edits and back-to-school posts.
