Russia at the Winter Olympics! They've only competed four times as a separate nation since the breakup of the USSR. And generally, they've been going downhill (zomg, I could totally insert a skiing joke here) since 1994.
They're not that great at skiing actually, but they kick ass at figure skating and cross country skiing -- presumably because Russia has a whole lot of cold stuff which is mostly flat. They're also pretty good at the winter
Biathlon which is without doubt the dumbest combination of sports ever put together into a combo event: cross-country skiing and shooting.
Oh, and in Soviet Russia, skiier shoots you!
