SCTV, EUF (stewardesses stripped of their uniforms)
 

The classic SCTV skit; Dr. Tongue's 3D House of Stewardesses. It may have been posted before, but this is the best quality version I've seen. "Bruno, take our guests' coats..now get their blouses and skirts!" A fun little skit. Credit to the original uploader.

Caps.

An interesting side note; the head stewardess in this clip is played by Catherine O'Hara (the mother from Home Alone).

Here's a more complete version of this clip. Unfortunately, it's not very good quality. The embarrassed screaming. The way the girls are spun around as their skirts come off. The fact that they're all extremely good looking (especially the young Catherine O'Hara), make this a comedic EUF masterpiece. The only flaw is the battleship plate armor underwear (but you can see their real underwear through the material of the costume underwear). If anyone has a better quality version, please feel free to post it.
