Apparently Tony Blair had to cut a chapter out of his book.
It said he used to jog most days, and he often passed a prostitute who would shout out "fifty quid" and he'd reply, "Fiver."
This happened quite often, and became a joke between them.
One day, Cherie accompanied him and he dreaded passing the prostitute, in case Cherie got jealous.
As they jogged past her, the prostitute shouted out,
"See what you get for a fiver"
