May I remind you of the old joke;-
A policeman, passing the park on a very dark night, heard a commotion in the bushes; he shone his torch, saw a couple `at it` hammer and tongs, and said (rather stupidly) what the hell are you doing?
The man looked up and said "shagging the missus";
The PC asked "do you often shag your missus in the park bushes?"
The man replied "I didn`t know she was my missus until I`d paid her and started shagging her"
