Expobank, a leading Russian bank, has pushed the boat out with their 2008 calender which features some of their female workers in scantily clad, risque poses. To be fair, it really does beat the Halifax adverts in the UK where workers sing and dance (think nails down a blackboard and you're close.)

"Stripping calenders" have been done to death but the real joy in this trend is of course the fact it is a leading Russian bank behind the calender. Much enjoyment can also be gained from the bank's press release about the calender where the reasoning behind the decision all becomes every so clear.
