In his debut stand-up special “American Boy,” Marcello Hernández unabashedly explores who he is and where he comes from through stories from his childhood in Miami to tales of culture shock in University Heights, Ohio. Much of his storytelling revolves around his experience with unmedicated ADHD through childhood to adulthood, making “American Boy” a quintessential get-to-know-you comedy debut. This tendency also lends itself toward a choice that is overused in Hernández’s comedy — his frequent use of yelling or exaggerated emotion as a punchline in and of itself. The most important and poignant aspect of Hernández’s comedy is his unapologetic pride in his Cuban heritage. The title of his special, “American Boy,” affirms both identities of his Cuban American community as just that — undeniably American — despite constant, violent efforts to portray them as outsiders.
