Linch likes to buy a packet of chocolate raisons and leave a few on kitchen shelves. He waits untill he hears the scream of
"Ewwww!!! Looks like a rat has left some droppings"
He will pick one up, look at it, then eat it and say...
"Yup, tastes like rat sh!t too!!!"
(I have done this, the look on peoples faces is priceless!!!)
