LEPRECHAUNS CAN'T EITHER:

Aliens can't hear us, says astronomer (Robin McKie, 1/27/10, Observer,)

At a special meeting on the search for extraterrestrial intelligence (Seti), the US astronomer Frank Drake – who has been seeking radio signals from alien civilisations for almost 50 years – told scientists that earthlings were making it less likely they would be heard in space.
