Hmm...is the first one Equestrian and the second one Gymnastics?

I think the top one is horse-racing or whatever the proper name is :P But with that sort of background it makes me think of some aquatic event.
And the second... um.. now this one looks like gymnastics as well...

The first one is probably an equestrian event (horse-back, well, dog-back riding?) and the second one is high jump?

First is Equestrian? I dunno if there is a sport with 2 riders though XD & Second is parallel bars :D

Well according to flikr its Equestrian and gymnastics. but does look more like a high jump.

and bah next set is up >.<

Something and high jumping...? O_o

The top one looks like water polo to me. :)
