When are the Olympics?
Aug. 5 - Aug. 21, kind of.
A few sports like soccer start on Aug. 3 because their tournaments take longer to finish. The opening ceremony, however, is on Aug. 5.
Who's lighting the torch?
It's always kept a secret, but most think Brazilian soccer legend Pelé will do the honors at the opening ceremony.
Where are all the Russians?
They cheated -- big time -- and paid the price. Over 100 Russian athletes have been banned from the Olympics, including the entire track and field team.
While it may sound like a famous one-name Brazilian athlete, Zika is a virus suspected of causing birth defects that has spread across the Americas, including Brazil. It caused many potential Olympians to back out of the games.
Who's NOT going to the Olympics?
So you don't embarrass yourself, here are some notable athletes who will NOT be competing in Rio.
Basketball: Steph Curry, LeBron James, Russell Westbrook, Kawhi Leonard, Chris Paul
Golf: Jason Day, Rory McIlroy, Jordan Spieth, anyone else you've heard of.
Tennis: Roger Federer, possibly Rafael Nadal (great ... the only two tennis players you know)
These sports really ARE NOT in the Olympics?
You're sure that these are Olympic sports. Guess again.
Baseball - last played in 2008
Softball - last played in 2008
Lacrosse - last played in 1908
Hockey (that's the Winter Olympics)
Video Games (not yet, at least)
