Well you know what they say....whatever floats your boat
I expect that’s a variation on the prisoner and priest joke which round here is claimed to have happened in Armley prison (which I doubt!).Two members of the Mafiosa are walking down some dark Chicago back streets in the middle of the night.
One turns to the other and says, ‘I must admit that I’m a bit scared’.
The other one says, ‘I bet I’m more scared than you, I’ve gotta walk back on my own !’
