The following joke was recounted recently on Greater Manchester Radio (GMR)

Two Liverpudlian young offenders are sharing a cell in Borstal. One is laboriously writing a letter. He looks up and says "Ay ! Ay ! How do you spell 'Daryl' ?"

"What you wanna know for ?" says his cell mate. "We don't know any c*** in 'ere called Daryl."

The first one says, "'Cause I want me mam to send us a pair of jeans Daryl fit me."

"You daft wassock!", says the second. "It's not, 'daryl' fit me. It's 'worral'."
