The whirl of office parties in December marks the onset of workers getting in late, bleary-eyed and clutching double espressos.

Others walk in the door post-party with their reputation in tatters and catch co-workers giving them strange looks as they make their way to the water machine.

For the final Office Life report for the year, we are seeking your Christmas party tales.

Send us examples of the more unusual gatherings you have been to. What happened after the drinks began to flow and the disco hits were turned up? Did the night of excess have any lasting effects?

The best and worst stories will be published in Office Life on Tuesday.
