BLUE EMU

I want to start a shopping list but I
never do because the first
item on the list will be
Blue Emu, which is a blue ointment in a
white jar and why anyone would name a blue
ointment in a white jar for a giant
flightless bird is more than I can
understand and instead of
writing the list I start
wondering about that. Blue Emu is
a wonderful ointment; it does
exactly what you want it to - makes pain go
away - but not if the jar is empty. Okay then, here's the
list: Blue Emu, Blue Emu, Blue Emu, oh and
maybe a bird book too so I can look it up and see
if there is one.
