Well I'm not sure this fits in exactly with this thread, maybe...but it's a little funny...
DH told me he got an 'offer' the other night. Right, so his employer's office (right now - they are moving next month after about 8 years at where they are now) is down the red light district side of Leeds - more of an issue at night, than during the day. Anyway, he had to go into the office on Thursday at 3 am for a new software release they were doing. He tried to park in the office's car park but it was barred shut, so then he was driving slowly and circling around trying to figure out where would be best for him to park... When one of the local girls came up to his window & asked if he would like some business. 'No.' Then she asked if he had any smokes. 'No.' And then she walked off. It wasn't something he came across - 'er, um, well it found him and he had to politely decline.

Other than that - sign-wise (back on topic?):
There's a sign in Leeds Hyde Park right now that was put up by the council. Originally, it said No Parking in the Park. It has since been modified to read
No F**k
ing in the Park.
And my favourite in the countryside not far from here:
