Question: How many albums had Southern Culture on the Skids released before releasing Dirt Track Date? Passage:The band appeared on The Tonight Show with Jay Leno in 1995, performing "Camel Walk" from their album Dirt Track Date, where Jay Leno jokingly said Drew Carey performed on drums. They also appeared numerous times on Late Night with Conan O'Brien. The song "Soul City" was heard in the 1996 film Happy Gilmore, as well as the 2005 Dukes Of Hazzard movie. The song "White Trash" is featured in the soundtrack for the 1996 film Beavis and Butt-head Do America. The song "Camel Walk" is used in the 1996 movie Flirting with Disaster, the 1997 movie Perdita Durango, and the 2009 movie Schwerkraft. It also was used on the first season of the TV show Psych in the episode "Weekend Warriors." "My Baby's Got the Strangest Ways" appears on the soundtrack to the 1997 slasher film I Know What You Did Last Summer. The band can also be seen performing the song on a beach party in the movie. Four of their songs, "King of the Mountain", "Pass the Hatchet", "Cheap Motels" and "The Corn Rocket" appeared on the soundtrack to the 2001 film Super Troopers. The song "Smiley Yeah Yeah Yeah" appears on the soundtrack to the 2004 Major League Baseball video game MLB 2005. The track "40 Miles to Vegas" appeared on the EA Sports video game NASCAR 07. The song "White Trash" appears in the trailer for the 2011 movie Goon. Rick Miller appeared on episode 174 of the Americana Music Show and described their 2013 release, Dig This! as being inspired by having to dig ditches around his Kudzu Ranch recording studio to fix its septic tank. "Weird Al" Yankovic featured a style parody of Southern Culture on the Skids entitled "Lame Claim to Fame" on his 14th studio album, Mandatory Fun.

Question: Which North American city hall building that used Superblocks was completed first? Passage:Superblocks are also used when functional units such as rail yards or shipyards, inherited from the 19th and early 20th centuries, are too big to fit in an average city block. A contemporary function which reflects ancient practices that also requires larger than typical blocks is the sports stadium or arena. Just as the Colosseum in ancient Rome, sports complexes require superblocks. The Providence Park stadium in Portland, for example, takes up four normal city blocks as does the equally large Greensboro Coliseum in North Carolina. Other contemporary institutions, establishments or functions that use superblocks are: city halls like Government Center, Boston and Toronto City Hall; regional general hospitals or specialized medical centres; convention and exhibition centers, such as Exhibition Place in Toronto and the Boston Convention and Exhibition Center; and downtown enclosed Shopping Malls such as Eaton Centre in Toronto, echoing the large gallerias of the 19th century. Cultural complexes, such as the Lincoln Center in New York City, often occupy a superblock achieved through the consolidation of regular city blocks. A recent superblock user is the merchandise distribution centre, which can range in area from one to ten city blocks.

Question: Of the grasses that the essex skipper eats, which is the longest? Passage:Eggs are laid in strings on the stems of grasses where they remain over the winter. The Essex skipper's favoured foodplant is cock's-foot (Dactylis glomerata), and it rarely uses the small skipper's favoured foodplant Yorkshire fog. Essex skippers' other foods include creeping soft grass (Holcus mollis), couch grass (Elymus repens), timothy-grass (Phleum pratense), meadow foxtail (Alopecurus pratensis), false brome (Brachypodium sylvaticum) and tor-grass (Brachypodium pinnatum). This skipper's caterpillars emerge in the spring and feed until June before forming shelters from leaves tied with silk at the base of the foodplant to pupate. Adults fly from July through August. Like most skippers, they are fairly strictly diurnal, though individuals are very rarely encountered during the night.
