Professional golfers make the sport of golf look easy, but it takes massive amounts of hard work and training to reach an elite level. Nike Golf launched "Enjoy the Chase" prior to the first major competition of the season, The Masters. The ad stars Rory McIlroy, who was chasing a career grand slam. He didn't win, but the chase won't stop. The 60-second ad follows McIlroy throughout his immensely regimented training routine: wake up, strength-train, run, golf, visit the chiropractor. Day in and day out, McIlroy chases the dream. He's not doing too shabby so far. Watch the ad here, created by Wieden+Kennedy Portland.

States United to Prevent Gun Violence (SUPGV), a nonprofit organization dedicated to making communities safer, released #GunCrazy, a PSA that shows real gun violence to unsuspecting moviegoers. Warning: this video is graphic and disturbing. SUPGV invited fans of action movies to a screening of "Gun Crazy," billed as a big-budget adrenaline rush. Hidden cameras were placed inside the movie theater to capture the reactions of folks as they watched real humans get shot. People looked away and mouths dropped open, since it was not the mindless entertainment they were expecting. In interviews done after the film, people expressed worry about the over-glamorization of guns in the world. See the video here, created by Grey New York.

To celebrate Kobe Bryant's retirement, Nike Basketball gathered all his haters to serenade Bryant with a tweaked rendition of Otis Redding's "I've Been Loving You Too Long (To Stop Now)." Fans, opponents and even sports commentators sang "I've been hating you too long to stop now," to Bryant, as he played conductor to his rivals. Bryant encouraged the negativity from haters, no doubt thriving on it. The ad aired on ESPN during Bryant's final game. Watch it here, created by Wieden+Kennedy Portland and directed by Mark Romanek.

The National Park Service (NPS) and National Park Foundation (NPF) launched an ad campaign to celebrate NPS' 100th birthday. A 30-second spot uses sounds found in national parks, edited together to create the "Happy Birthday" tune. Listen for a Park Service Ranger whistling, a bell ringing, a bee buzzing, a bird chirping, a floor being waxed, a tent zipper being opened and a fly fishing line being cast, combined to sing happy birthday to the NPS.

Priceline.com launched "Whatever's On The Line, Priceline," an amusing campaign in which the brand weighs the pros and cons of taking certain trips. In the first ad, a woman is unsure if she should attend a destination family wedding. If she doesn't, she might hook up with a distant cousin. See it here. A couple looking to adopt a child overseas visits the boy in his native land first. Good thing, because the boy is more like a 30-year-old man. Crisis averted. Watch it here. A busy grandson wants to delay a trip to help his grandma, but if he doesn't show, a thief will gladly take his place. See it here. A final spot, "Life Lessons," stars former NBA players Latrell Sprewell and David Robinson. A dad ponders taking his daughter to the NBA All-Star game, which isn't cheap. There, she gets solid life advice from Robinson. If they don't go, the pair watch the game on a sports-bar TV, hearing Debbie-downer advice from Sprewell. Watch it here. BBDO New York created the campaign.

Finally, a golf ad I can relate to. Golfsmith launched a TV campaign aimed at us regular folks who enjoy playing golf but aren't very good. The 60-second ad follows golfers and their inner monologues as it's time to make an important shot. Sometimes, we psych ourselves out and a shot that seems too easy to miss becomes a hot mess. Despite the challenges, lovers of the game keep coming back and will do "Anything For Golf." Watch it here, created by Preacher.
