Dr Salla might be on to something. Last night on the way back from the
pub (in Derbyshire, UK) I saw a man leaning against a lamp post. A
steaming jet of alien protoplasm appeared to be gushing from his
mouth.  I said "are you OK?"

He replied "Fffuuuukkoofffff y'fukahhhh"

No HUMAN vocal cords could have made that noise - he MUST be one of
the mysterious 16 alien races.

NB.  US readers may want to google "David Icke". In the UK he has
written many books. His disclosures include the fact that Queen
Elizebeth 2nd' mum was actually a 10 foot tall alien shape shifter.
