I don't remember this one being posted before. I've never seen this film but this clip is one of my favourites:

Main bra stuffing action is briefly at the very beginning and then again (the exposure) from around 4:30. There's plenty of other artifice shown during the clip though.
The clip is in German but if you want to know what they're saying then the full movie in its original English is here:
