What I did I say? Look at him swinging that thing around like a rubber sword. He could have someone's eye out/head off.
A comedy magazine called Cracked I think it was (wish I still had it) which was similar to MAD - did a satire on this scene. Luke stands facing Ben and activates the sabre. Goes straight through him! Kenobi spends the rest of the adaptation with a large Elastoplast on his front and back. "Just a scratch my boy".
Very English.
