Well, actually, we have two sports we learned from you, Earthlings. Well, that and the whole concept of "sports" to begin with. No other species in the known galaxy has thought of so many ways to play with balls or knock them about.
The first sport we picked up from you is Frisbee. The second is disc golf.
We're not sure, but we think that Earthlings playing with flying saucers may be subconsciously related to abduction experiences. I guess it depends on how deeply the inventors were probed.
There's a new one few have heard of yet called "bucket disc." We're still waiting for that one to take off.
Meanwhile, we use the other two sports as drivers' ed simulators for baby Paliens!
