Oh nearly forgot
Once had to drive a few people up to York to a training thing. One of them, Lee was riding shotgun. As we entered each village on the way, you have to drive over a set of 3, 2 and then 1 ridge across the road (or is the other way around). I could see out of the corner of my eye he was thinking of something. Then he pipes up:

You know those lines across the road" he asks
"Yeah?" I reply
"Is it so blind people know when to slow down?"
I was too shocked to burst out laughing. "Like Braille? Yes they are"
The ones in the back were not so shocked to laugh and guffawed thoroughly

The numbers on the keypad on the drive to access the underground car park - only the underground car park, there's a separate pedestrian entrance - at a friend's block of flats have braille on each key and a separate message underneath in braille...
