 Question: can you have a heart attack from laughing Context: The show follows antique and collectible pickers Mike Wolfe and Frank Fritz who travel around the United States to buy or ``pick'' various items for resale, for clients, or for their own personal collections. They originally traveled in a Mercedes-Benz Sprinter van and now a Ford Transit. Danielle Colby runs the office of Wolfe's business, Antique Archaeology, from their home base in Le Claire, Iowa, and more recently at a second location in Nashville, Tennessee. Fritz sells his acquisitions at his own shop and on his own website, Frank Fritz Finds, upriver in Savanna, Illinois. The men go on the road, not only following up leads that Colby has generated, but also ``free-styling'' - stopping at places that look like they might hold items worth buying. They also pick some places more than once.
 Question: are mike and frank from american pickers brothers Context: There is no legal statute specifically prohibiting the carry of a firearm other than a handgun (pre-1899 black powder weapons, and replicas of such, are not legally firearms in Texas). However, if the firearm is displayed in a manner ``calculated to cause alarm,'' then it is ``disorderly conduct''. Open carry of a handgun in public had long been illegal in Texas, except when the carrier was on property he/she owned or had lawful control over, was legally hunting, or was participating in some gun-related public event such as a gun show. However, the 2015 Texas Legislature passed a bill to allow concealed handgun permit holders to begin carrying handguns openly. The bill was signed into law on June 13, 2015, and took effect on January 1, 2016. A License to Carry (LTC) is still required to carry a handgun openly or concealed in public.

In these compounds, at least one carbon atom is replaced by one of the heteroatoms oxygen, nitrogen, or sulfur. Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one nitrogen atom.

With a mainland area of 2,780,400 km (1,073,500 sq mi), Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking nation. It is subdivided into twenty-three provinces (Spanish: provincias, singular provincia) and one autonomous city (ciudad autónoma), Buenos Aires, which is the federal capital of the nation (Spanish: Capital Federal) as decided by Congress. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over part of Antarctica, the Falkland Islands (Spanish: Islas Malvinas), and South Georgia and the South Sandwich Islands.
