April Fool Marketing: Learn Klingon, Spray Yourself with Cheeteau

It's time for a new crop of viral-ready "April Fool's Day" marketing tricks to make us smile and share with friends.

• ThinkGeek wants you to buy its new exclusive Rosetta Stone software to learn Klingon (see right). Click to buy and you can earn 8,210.3 Geek points. Who needs this product? ThinkGeek helpfully notes: "Klingon may be a difficult language for humans to wrap their smooth heads around, but it's made even more complicated by the constant threat that saying the wrong thing might accidentally land you in a battle to the death."
• Google Maps invites you to become a Pokemon Master and help round up the hundreds of wild Pokemon out there in the wild. "We value employees who are risk-taking and detail-oriented, have deep technical knowledge, and can navigate through tall grass to capture wild creatures. It turns out that these skills have a lot in common with another profession—that of the Pokémon Master."
• Google+ is offering "Auto Awesome Photobombs" that may, if you're lucky, insert David Hasselhoff into your uploaded photos. Check out the hashtag #Hoffsome.
• UK grocery chain Tesco is marketing the Cudl, the world's first couples tablets. You and a loved one are never far from each other with tethered Cudl tabs. But Tesco also offers the Hudl tablet for real.
• Frito-Lay wants you to spritz yourself with a little Cheeteau "prestige fragrance" to carry the aroma of freshly-baked Cheetos wherever you go. See below. "Unexpected...Undeniable." Well, cheesy, anyway!
