the yellow bird one... the way i learned and i what i believe is a more humorous way of saying it went like....
a yellow bird
with a yellow bill
was sitting on
my window sill
i lured him in
with a peice of bread
and then i smashed
his little head
the doctor came to check its head
he said this bird
is surley dead
the moral of
the story is
if you want some head
get some bread
