I don't remember the details but this was, surprisingly, shot in a prestigious European opera house. It's actually part of an opera (my guess is the pieing/caking is not written in the opera per se but it was at least a regular part of this specific production.) I discovered this a few years back and actually found brief clips of the pieings from at least two and maybe three different performances. (One was shot from the audience and was not good quality.) I'm pretty sure the still you posted is a screencap from the more professionally shot video I found, which was a montage of moments from the whole show. When I have time to search my hard drive for this stuff, assuming I can find it, I will post it here unless someone else beats me to it. The woman getting caked is an opera star and a very attractive woman with a stellar figure. I remember finding some comment from her about the variability of the pieings she took from one performance to the next.
