An old Nottingham senior citizen, found one of his hearing aids were not working after having used the same set for 12 years.
He went to have them looked at, and the man convinced him that if he bought a pair of the new mega-digital ones, it would improve is hearing no end. So he reluctantly paid the £500 demanded, and ordered them.
When they arrived, he put them in, and boy did he think they were good. So exited by this, he went round to his neighbour to tell him how brilliant they were;
"Bert, Bert, I've got me new 'earing aids, state-of-art they are, mind you they did cost me £500, but the're perfect!"
"Really," answered the neighbor. "What kind is it?"
"Twelve thirty" he replied!
