Assuming alien races are monitoring our TV/radio transmissions and basing their impressions of our species on what they see, they’re likely to be surprised by some of our actual needs and habits.
For instance, the will not expect any of these things:
Going number 2.
Sleeping for more than 30 seconds.
Unattractive people having sex.
Children who are unable to instantly come up with witty retorts
Unicorn McGriddle, I look at it like this: When I go to Japan I am going to be thoroughly surprised if there aren’t Japanese men and running around dressed like giant penises and pissing in the streets in front of adoring phone-cam-wielding crowds of excited spectators.
Going number 2 is going to be classified as a horrid disease that first occurred in the 1990s, and South Park will be viewed as a documentary on that horrific ailment.
The aliens will flee once they are confronted with Big Brother-style reality TV.
They’ll wonder why we all live on land, while there’s more room in the water.
Not sure what they’ll think of Brokencyde.
