 Question: can you have a heart attack from laughing Context: The signage for advisory speed limits is not defined by the Vienna Convention on Road Signs and Signals, and is therefore not standardised internationally. The United States uses a small yellow sign under the main warning sign, as well as a standalone variation on the standard speed limit sign, with a yellow background instead of a white one, the words ``speed limit'' omitted and an additional panel stating the type of hazard ahead. Though they list speeds, the U.S. advisory speed signs are classified as warning signs, not regulatory signs, as primary speed signs are. Australia uses a similar design as the U.S. in spite of regulatory speed limit signs being quite different. Germany used a square sign with a blue background and white lettering, similar to the minimum speed limit sign, and New Zealand uses a yellow background with black lettering (similar to the Australian design without the ``km/h'' lettering). The United Kingdom currently uses an oblong white rectangle with black lettering stating ``Max Speed''.

In addition, all no-hitters that were broken up in extra innings or were in shortened games are listed, although they are not currently considered official no-hitters. (Prior to 1991, a performance in which no hits were surrendered through nine innings or in a shortened game was considered an official no-hit game.) The names of those pitchers who threw a perfect game no-hitter are italicized. For combined no-hitters by two or more pitchers on the same team, each is listed with his number of innings pitched. Games which were part of a doubleheader are noted as either the first game or second game. The most recent no-hitter was pitched by Edinson Vólquez of the Miami Marlins on June 3, 2017.
