Very funny.  It trashed my tty.  Even reset won't restore the
settings.  Anyway.

I chose the Google logo on the Google homepage because I know we
try really hard to conform to standards, so we can have the biggest
possible user base.  Micro$oft or Yahoo! probably would have come
out the same way.  Or some image on kernel.org.

Anyway, I didn't send any browser data, so the server had to assume
the dumbest f'ing browser on the planet, and I got back binary data.
