This series is inspired by Amedeo Preziosi's YouTube sketches, especially the "Fumagalli", "Fumagalli e il Pancio" and "L'atmosfera in classe" series.
Character Makì is inspired to Amedeo Preziosi's fictionalized self in the original "L'atmosfera in classe" shorts, who when questioned by the Prof or when the latter said something, often repeated "Ma chi?", meaning "But who[ are you telling/asking that]?", though the web-series's Makì, greatly redesigned, says it mostly to someone at the phone or the singing voice trying to sing "Hello" by Adele.
