From the movie Get Smart, Agent Smart receive a Swiss Army knife that have a harpoon like device with spider's web as it's rope. the creator (the cast from heroes) with his friend said that the rope was made from milking spiders!! Is it true that you could actually milk a spider for it's web? hahaha....

Spider web was used as the crosshair in gunsights in WW2.
Nowadays, unlikely.
My favourites from the original Get Smart were the Cone of Silence and the Shoe Telphone. And Agent 69.

They really used the spider web as a crosshair? How do they milk a spdier actually? and how much did they need for a single crosshair? hahahaha..... Yes, the cone of silence is actually pretty cool!! Agent 69 is the one played by Anne Hathway right? She's really hot in that movie!! hahahaha....
