Black Black (Burakku Burakku) is a brand of caffeinated chewing gum produced in Japan by Lotte. It has been sold since 1983. and is popular in Japan, partially due to its well-known television commercials that star Jean-Claude Van Damme. It became popular in the United States after being mentioned in Wired Magazine. The gum's name is derived from its charcoal-like color. Ingredients include sugar, starch syrup, grape sugar, erythritol, oolong tea extract, ginkgo extract, chrysanthemum flower extract, gum base, flavorings, coloring agents (cacao, gardenia), caffeine, and nicotinamide. A persistent urban legend holds that the gum contains nicotine, the misconception stemming from confusion with nicotinamide, a different substance related to the B vitamins. The packaging contains some strangely phrased Engrish on the label that reads, "HI-TECHNICAL * EXCELLENT TASTE AND FLAVOR". Some sticks also say "YES, CHEWING!". In the United States, Black Black may be procured through a variety of mail order and online companies and in many Asian supermarkets.

Bob the Builder is a British children's animated television show created by Keith Chapman. In the original series Bob appears as a building contractor specializing in masonry in a stop motion animated programme with his colleague Wendy, various neighbours and friends, and their gang of anthropomorphised work-vehicles and equipment (all made of clay). The show is broadcast in many countries, but originates from the United Kingdom where Bob is voiced by English actor Neil Morrissey. The show was later created using CGI animation starting with the spin-off series Ready, Steady, Build!. In each episode, Bob and his group help with renovations, construction, and repairs and with other projects as needed. The show emphasizes conflict resolution, co-operation, socialization and various learning skills. Bob's catchphrase is "Can we fix it?", to which the other characters respond with "Yes we can!" This phrase is also the title of the show's theme song, which was a million-selling number one hit in the UK.
