If the alien "Greys" from Zeta Reticuli ,or the "Ebens" from Serpo, want us to know what they're like...

and they don't want to cause panic among the weak-minded, they should do a "reality TV" show for broadcast on Earth.

It should show a typical home situation on their world, what they have for dinner ( winged purple rodents ), domestic disputes over infidelity ( sex with a mother-in-law ), a goofball good-for-nothing son ( who astral travels to Earth ), and a daughter who pretends to be studious, but is really a slut ( despite her oversized bald head ).

It could be modeled after "Married With Children" or "The Simpsons".

We would grow to understand their culture, and soon the public would demand a "trade".

We give them Al Gore, George Bush, Rosie O'Donnell, Paris Hilton, Michael Moore , and in return...well, we don't ask for anything in return, we just thank them.
