I personally find car registration numbers easy to remember. I can  
still remember the registration number of my parents car from the mid- 
sixties. One of my 'random but memorable' password schemes is to  
stand at the road side and record a few registration numbers,  
memorise them and use the concatenated reg numbers as a password.  
Calculating the entropy of a UK car registration number is left as an  
exercise for the student.
