After they reach 2025 and are about to enter the convenience store, someone gets into a DeLorean automobile and drives off - the time machine used in the movie "Back to the Future".

The statue of President Miguel Alemán referenced in the film symbolizes much more than a tribute to a political figure; it represents a period in Mexican history marked by tensions between institutional power and dissenting voices. Before its final destruction, the statue was the target of at least two bombing attempts - in 1960 and 1965 - reflecting the growing discontent toward the presidential figure, especially among university circles. In 1966, it was ultimately demolished with four charges of dynamite, reducing it to rubble. This act was not mere vandalism, but a politically charged statement. Later, during the 1968 student movement, the remains were transformed into a collective canvas by artists and intellectuals, turning what was once an official monument into a testimony of protest art and the fight for freedom of expression.
