Will some Briton please explain to this poor American what’s so funny about a Police station with an address of 999 Letsby Avenue? I understand that the American equivalent would be 911 Letsby Ave. (999 being the British emergency number), but that doesn’t seem to help. This apparently is a pun, but perhaps I have the wrong accent to get it. (And I usually don’t have much problem with British humour.)
999 is the number you dial to talk to the emergency services.
“Lets be ‘avin’ you” is what policemen supposedly say when they arrest someone who is reluctant to come quietly (I don’t expect they ever commonly said this - I should think it arose in comedy on the stage or screen somewhere)
eh, wot’s this then?
Evenin’ all.
What’s all this then?
You’re nicked sonny.
I didn’t mean no trouble, guv’nor.
