Seems the entire world finds itself on babywatch today, as Catherine, Duchess of Cambridge, went into labor Monday. "Kate," of course, is wife to Duke of Cambridge and heir to the British throne, William. We'll have full coverage right here in our unique Guinness World Records way once the birth is officially announced, so keep checking back. But for now, get all caught up on everything royal birth with a handy recap on all that's happening.

Elsewhere on the British Isles over the weekend, Phil Mickelson (pictured above) stormed from five shots back after the third round at Murfield Golf Club of The Open Championship (aka British Open) to win his first Claret Jug over the weekend. Among the many interesting statistics found on this page over at ESPN, Mickelson is just the third golfer in the last 100 years to be down that many strokes going into the final round and to then win by at least three. An absolutely stunning performance that made "Lefty" (aged 43) the oldest player to win a major since Ben Crenshaw won the 1995 Masters, also at 43. The oldest player to ever win a golf major? That's Julius Boros (USA), who won the 1968 PGA Championship at age 48.

A since-been-removed tweet from television personality Geraldo Rivera caused a social media stir over the weekend, as the 70-year-old shared a topless photo of himself with the world. He appears to be in awesome shape, which is no surprise, as more and more people stay fit late into life. Although while Rivera certainly impressed, he still has a while to go to match our oldest bodybuilders on record: Raymond Moon (male) and E. Wilma Conner (female) who competed in professional bodybuilding competitions at ages 81 and 75, respectively. Here's video of the incredible Moon from a few years ago.

Lastly, in the winner for weirdest story of the weekend, American college football player Antonio Morrison was arrested for barking at a police dog Sunday. What we don't know from the story is whether Morrison was trying to beat the record for loudest bark, which hit 113.1 dB by Charlie the golden retriever at the Purina Bark in the Park event in Rymill Park, Adelaide, Australia, on 20 October 2012.
