If it seems like Korean pop senstation PSY has been everywhere the last year, maybe it's too good to be true.

Turns out a PSY imposter has been strutting his stuff at the Cannes Film Festival. But, fear not, the real PSY turned into a bit of a Psylock Holmes before announcing, simply, on Twitter that " #realPSYinSingapore."

Of course, who wouldn't want to pretend to be the global viral sensation? PSY is owner of a slew of records, including most viewed video online and most liked video online for his 2012 hit "Gangnam Style."

The city of Prague aims to help all those people looking for love in all the wrong places. Train operator Ropid is currently polling to see if there's interest in a metro carriage strictly for singles to meet each other on the ride to and from work. Meeting that special someone for a lengthy flirt surely wouldn't fly for a few of our speedier metro record holders, including Chris Solarz/Matthew Ferrisi and Andy James/Steve Wilson. They set records for the fastest time to travel to all of New York City's subway stations (22 hr 52 min 36 sec) and all of London Underground's stations (16 hr 29 min 13 sec), respectively.

Two men are now claiming to be the oldest to claim Mount Everest, after 80-year-old Japanese climber Yuichiro Miura reached the summit Thursday. While Guinness World Records HQ awaits his evidence, Nepalese climber Min Bahadur Sherchan plans to reach the summit at age 81 in just a few days. Amazingly, Miura has held this record twice before, while Sherchan's is the current official holder. Here's a photo of him and his team on his trek from 2008.

Lastly, McDonald's wants to make sure you're consuming enough calories. The iconic "Golden Arches" has released a menu item called the " Mega Potato" in Japan. It's an order of fries twice as big as a large order and clocking in at an astounding 1,142 calories.

Pair that with our record holder for the most calorific hamburger commercially available -- Heart Attack Grill's 9,982-calorie Quadruple Bypass burger in Las Vegas -- and you have 5.5 days' worth of calories in just one sitting. Somebody pass us a Coke!
