Tiger Woods and Lindsey Vonn have been seen in public on several occasions since they started dating, but most images of the couple have been rather serious.

This week, Vonn wanted to change that.

The Olympic skier and the world's most popular golfer were sitting on a golf cart together on the golf course when Vonn decided to pull a prank on her boyfriend by placing a baby squirrel on his back when he least expected it.

Davis Love III had the baby squirrel tucked away in his pocket and handed it to Vonn. Woods was paying close attention to the golf course and didn't seem like he wanted much to do with the whole thing. Check out the video of the whole thing below.

In other news, Vonn said she is much further ahead of schedule than anticipated as she recovers from a torn ACL and MCL she suffered eight months ago. She said she will be traveling to Austria for the World Cup opener at the end of the month and she plans to compete in the upcoming 2014 Sochi Winter Olympics in Russia.

"It's a matter of getting up to 100 percent speed and being able to push it as if I were racing, and I haven't quite done that yet," she said in a videoconference interview with reporters at the U.S. Olympic Summit. "Waiting for those last steps before taking the plunge to racing again."

Meanwhile, Woods is enjoying success at the Presidents Cup. He partnered up with Matt Kuchar and did a special handshake reminiscent of "The Fresh Prince of Bel-Air" TV show.
