ignoring the work on my desk i wonder: what makes an olympic sport?

i've come up with rough categories:

Can YOU Do That? (aka, The Wheatties Box Sports): Track & Field, Gymnastics, Weightlifting

Tough n Grunty (it's like extreme PE): Tennis, Wrestling, Boxing, Swimming/Diving, Soccer, Rowing, that biking thing, speedwalking, Canoe/Kayak, Beach/Volleyball, Field Hockey, Tae Kwan Do, Judo (basically anything involving kicking and punching), Basketball, Softball

AristoLame (things you can do at a tea party - or people did at estates in the 19th century): Fencing, Badminton, Synchronized Swimming, Equestrian, Ping Pong (that's what it's called, people!), Shooting & Archery (it's target practice) ...

I'm forgetting others but I think that category 1, half of category 2 and only 1 of category 3 should be in the Games.
