Unusual photos from a beach vacation.

This is the pinnacle of buddy culture, beach style. A group of guys hanging out under a ridiculously small umbrella, clearly not there to sunbathe. Maybe they're avoiding their girlfriends, maybe they're planning a guys' getaway, or maybe they're just deeply committed to the art of effortless relaxation.

Whatever's happening beneath that tiny shade structure, one thing's for sure: Rihanna's "Umbrella" is now stuck in our heads, too. These guys have perfected the sacred ritual of relaxing with friends at the beach.

Hats off to whoever came up with this clever idea for the Sprite ad—replacing the iconic soda with water is a catchy twist. But the real story here? The creepy guy in the background.

Hiding just a little too intensely behind two women, he looks like someone who's strayed into a completely different gender. Sure, maybe it's all in good fun, but the vibe is... weird. It reminds us that even the best advertising concepts can be hijacked by a creepy stare.
