Prompted by Andy_J and his V-Strom in Lincolnshire I googled 'Why is Lincolnshire so flat?' and got this joke, told by David Cameron apparently:
A man moves to Lincolnshire, and is lonely until he gets a visit from a local farmer.
The farmer invites him to a party, but warns him there will be a lot of heavy drinking.
The man agrees that a bit of booze is likely to help lubricate the evening, and help him make friends.
The farmer warns there will probably be a lot of fighting, but that doesn’t deter the newcomer.
Finally, the farmer says the evening will probably end with “a lot of rough sex”, but the new arrival shrugs and supposes that’s as good a way as any to get to know people in the community.
As the farmer turns to head home, the man asks him what he should wear.
The farmer says: “You can wear whatever you like, because it’ll just be you and me.”
