If you see this episode (where Xena has to save Helen of Troy, and yes, they have the Trojan Horse in it), wait until near the end when Xena is outside Troy's walls, fighting Paris' brother (whom I forget his name). He pushes her against a boulder...but, you can clearly see that the boulder cushions her - Xena's body is pushing the rock down. Apparently, they need to make harder rocks, because it was so obvious it was fake. It's pretty funny!
