Besides the dodgy cracker jokes, be wary of vigorous bear hugs, heavier-than-expected nieces and elastics demonstrations for the grandchildren on Christmas.
ACC has received 3238 claims totalling almost $850,000 from Christmas Day accidents.
The biggest Christmas injury culprit was falling with it being mentioned in more than half of those claims.
But some mishaps were a little more left field.
One person was left nursing bruised ribs after what was described as a vigorous bear hug, while for another, pulling a Christmas cracker ended in an eye injury and a third person strained an elbow by picking up a heavier than expected niece.
