The image in question is a photoshopped parody of the famous Mount Rushmore National Memorial, humorously labeled as "Mount Touchmore." Instead of the four U.S. presidents that traditionally adorn the side of Mount Rushmore, the edited image features the likenesses of four men, superimposed over the original sculptures.
One aspect that might contribute to the humor is the play on words seen in the faux monument's name, "Touchmore," which is a pun on the real monument's name, "Rushmore." Puns often serve as the basis for humor as they play with language and meanings, leading to unexpected connections.
Instead of solemn presidential faces, the figures depicted in the image are striking emotive poses, which stark contrast to the dignified and stoic expressions carved into the actual granite faces of Mount Rushmore. This incongruity between what is expected and what is presented can provoke amusement.
The photograph is in black and white, which could be seen as adding a layer of nostalgia or historical feel to the image, while simultaneously contrasting with the modern and whimsical content added. This contrast between old and new can evoke a chuckle as it plays with the power of iconic imagery peppered with modern pop-culture references.
Another reason why people might find it funny is that the re-imagining of such a patriotic and significant American monument with these particular individuals' faces might be considered absurd and subversive, amplifying the comedic effect by tapping into themes of irreverence.
Lastly, it is worth noting that humor is subjective, and while some may find the playful and irreverent nature of the image to be funny, others may have a different reaction based on their personal perspectives and sense of humor. Mount Touchmore
