This topic has been brought up before, but I think I found another, new (short) scene.

Travesties is theater production that may or may not have a pie fight between 2 pretty ladies.

The pie addition is at the discretion of the director and his/her "vision" of the play.

I did find a quick but cute instance of the "pie vision"

It is a trailer for the production, so it is quick, but you do get some aftermath and reaction

The pie scene is at the 3:54 mark.
