The Department of Festive Affairs has issued its annual report on Christmas.

The survey reveals a 10% year-on-year decline in debriefing by staff in stationery cupboards at office parties.

A DFA spokesperson explained: "The decrease in this festive fumbling is partly due to fewer people having office jobs and fewer companies holding parties. The main reason is that with paperless technology, offices no longer have big enough stationery cupboards. However, on a like-for-like basis there was a broadly similar level of debriefing in locations such as the sofa in the managing director's office (after he had gone home but told the staff to stay on and enjoy themselves). The broom cupboard, underground car park, and up against the filing cabinet in human resources were also deemed fit for purpose."

On the health front, the DFA warns a Christmas Day limit of 12,000 calories may have to be introduced. Many Scots consumed their full five a day: an entire Cadbury's selection box, a pyramid of Ferrero-Rocher, a bag of Mrs Tilly's tablet from Tesco, a tin of Celebrations, and a chocolate partridge in a pear tree. These sweeties were in addition to a large Christmas lunch which, statistics show, typically featured sage and onion stuffing inside a turkey wrapped in streaky bacon inside an oven at gas mark 7. "Turkey's popularity remains a puzzle, a mystery and an enigma," said the DFA spokesperson who prefers a rib of beef.
