Do the mario!

A man in a red shirt and light-colored pants stands against a vibrant, shifting background of pink, purple, and blue light, repeatedly pulling his pants down to his knees and then pulling them back up in a rhythmic, dance-like motion. The scene cuts to a pair of white pants hanging against a green screen, then to the man in a white shirt and dark pants performing a similar action, followed by a blurry shot of a person in a red shirt, and finally returns to the man in the red shirt and light pants completing the loop.
