A mentally retarded Shit Stained Schumacher that is my great uncle. We call him SNUF (Special Needs Uncle Fred). He is the legend that supplies us with our SNUF Bags with 20 packets of lovely Hill Biscuits in each one. When there is a beeping noise that is really getting on his nerves, he will decribe it as "BANG, BANG, BANG!" while using the F word excessively. He has an unbeleivably high amount of certain household objects such as: 84 bog rolls, 13 bags of sugar, 100 yellow dusters for drying the pots and for his cap, 1100 tea bags, 800 weetabix, and 100 packets of Hill biscuits.
Lets look in the SNUF Bags, woohoo! A bag of crisps! And, ahhh, only 20 packets of Hill Biscuits. Why Willo, WHY?????
