Yes, whatever the heck jeu de paume is
Jeu de paume, or "Real Tennis" as its called in the UK, was a Summer Olympic sport in 1908. Frighteningly, the more modern Olympics include fake tennis as an event. Or as we call it: Tennis.
Rollerball is not a sport...yet
Rollerball only exists in the future as imagined by the 1975 science fiction movie Rollerball and its 2002 remake.
Fencing is only one of four sports that has been included in every Summer Olympics since the rebirth of the modern competition in 1896. En garde!
Trampoline is a summer Olympic sport and has been so since the year 2000. Y2K!
Badminton is a current summer Olympic sport. Birdies and all.
Biathlon is a winter Olympic event. You may have confused it with Pentathlon, which takes place in the summer.
It's new, but yes!
Rugby sevens is a new Olympic sport! The first Olympic rugby event will take place in Rio in 2016.
Bandy WAS a winter Olympic sport for one lonely year (1952). Considering it's basically ice hockey with a ball instead of a puck it's easy to see why it was phased out.
Tug of war was a summer Olympic sport from the year 1900 to 1920, after which tugging your way to a gold medal became impossible.
Was This Actually A Summer Olympic Sport Or Nah?
Oof, you don't know your summer Olympic sports very well, but that's OK! Keep an eye out during Rio this year to brush up on your knowledge.
You know some stuff about the Olympics! Nice. If you're miffed about being second place, remember that you basically won...except for the people who came before you.
AMAZING. You know a lOT about the summer Olympics! I bet you already have plans to sit down and watch as much of Rio 2016 as possible. Great job!
