Star Wars Episode 6: Return of the Jedi - Zap! Sorry, Princess...
After Princess Leia has choked Jabba with her chain, she runs down to R2D2 and he breaks off the chain around her neck. Not a problem.
Except... he "cuts" off the chain with a bolt of electricity. I would have thought that the princess attached to the end of this *metal* chain would have been somewhat uncomfortable with this...
