That seems a fair question, considering how boring the Olympics usually are. However, I've been tuning in daily and I find a lot of these sports fairly compelling. As of publishing this article, the medal count stands as this.
Weightlifting: Seeing a guy dislocate his elbow while trying to lift 325 pounds above his head is both gruesome and awesome.
Synchronized Diving: Impressive, but not as cool as swimming.
Just for the record, I also watched a little tennis, but tennis is always interesting so it doesn't count.
