A particullarly cheap meat and vegetable pie that when turned upside down and the bottom pastry is eaten off it looks like you've indeed actually eaten a rat pie. This can be further demonstrated by a line of tomato ketchup from the base of the pie to act as a tail.
I would have loved to have taken you up on the offer of a pork pie but I've already had Rat Pie for lunch.

'Slime looked at the grey skies and knew that today was a day for a pie. He started his Harley and headed south. Yes, the journey would be long, cold and not a little dangerous but there was a pie to be eaten and it had to be done. He is a Pie-Rat and it is the law'.
