This classic Just for Laughs Gags prank features a performer dressed in a green alien mask and a black cloak hiding behind park bushes to startle unsuspecting pedestrians. Most passersby react with predictable jump scares and laughter, including a young man in a yellow beanie who hilariously abandons his companion and sprints away when the alien pops out around 0:25. The upbeat accordion soundtrack and canned laughter keep the mood light as various couples and students walk into the trap.
The funniest moment happens at 1:12 when an older gentleman in a tan coat and flat cap walks past the hiding spot. When the alien leaps out and makes dramatic scary gestures, the man doesn't panic at all—he just stops and stares back with total apathy. The alien tries one more roar before realizing it isn't working, awkwardly shuffling off in defeat around 1:24. It's a quick, lighthearted gag that works so well precisely because of the old man's completely unbothered reaction.
