Three men stand side-by-side in a static image; the man on the left has a cartoon face superimposed over his, with large, round eyes and a wide, smiling mouth, while the other two men have normal facial features. The image is overlaid with large, red, stylized text that reads "a-haaaaa" and "aaaaa" repeated multiple times, with the text and the men's faces remaining completely still throughout the loop.
