Yes, he did. You must own one of TomTom's satellite navigation systems and purchased TomTom's PLUS service so that
you can download additional nav voices. The company has been offering additional downloadable nav voices for a while
now and has just signed a deal with John Cleese to lend his infamous oratory to your daily drive. John Cleese's voice
will cost you $12.95 and is available in either meters or yards. Man, do you think he had to sit in a sound booth and
recite every street name and increment of distance in both meters and yards? Anyone know how they do that?
I could end this post with some appropriately hilarious line from Holy Grail, but I've only seen it once and that was like 10 years ago. Sorry.
