'Ere - I know a Norman yolk:

This Norman walks into a Saxon bar, and says, "Pint of mead, please - and make it quick". The Saxon barman looks hard at the Norman, serves up the mead and says, "That'll be 34 groats please". The Norman pays up with a bad grace. After a bit the Saxon says, "We don't get many Normans in here." The Norman says, "At 34 groats a pint, it's no bleedin' wonder!"
