The image presented is a meme that plays on the juxtaposition of two dates, April 19 (4/19) and April 20 (4/20), using facial expressions and symbolic imagery. It's a split-image meme with the top half showing a man with an exaggerated, somewhat confused or inebriated facial expression, alongside the text "4/19". The bottom half of the meme has the same man, displaying a similar goofy expression but presumably intensified, next to the text "4/20", which is stylized with cannabis leaves replacing the numbers "420".
The humor in the image largely derives from the cultural significance of the number 420 in cannabis culture, which is celebrated as a time for marijuana enthusiasts to indulge in their favorite herb, especially on April 20th. The transition from 4/19 to 4/20 in the meme implies a transformation or escalation associated with the consumption of cannabis, suggested by the man's intensified expression from the top to the bottom image.
The choice of facial expressions in both halves of the meme is crucial to the joke. The man's expression on the left side appears to be casually bemused or spaced out, while that in the right side suggests a deeper level of intoxication or bliss, perhaps alluding to the effects of consuming cannabis, which is typically associated with mellowing effects, hunger, and altered cognitive and sensory perceptions.
The usage of the cannabis leaf in place of the zeros in "4/20" on the bottom image acts as a direct visual cue, leaving no doubt about the reference being made to marijuana. It ties the change in the man's expression directly to the culture and practice of smoking cannabis on this particular date, thus reinforcing the punchline.
That the meme only changes the date from 4/19 to 4/20 and alters nothing else visually underscores the sudden and humorous shift that is being suggested. This use of minimal change for comedic effect is a common trope in memetics, where the audience is expected to infer a significant transition from a minimal cue.
Why people might find this funny depends on their familiarity with and attitude toward cannabis culture. Those who recognize and appreciate the 420 reference may find humor in the exaggerated portrayal of how one might transition from a state of pre-celebration to full participation in the cannabis-centric festivities of April 20th. It plays on the cultural ritual and the stereotypes associated with cannabis consumption, while relying on the universal language of facial expression to communicate the joke. 4 19 4 20
