I just saw this movie and it was kind of stupid but there was a riddle that I never saw answered and I can't figure it out. It was something like this:

What does a spider weave?
It has no eyes, but it can see.

I'm not sure if that's the exact wording but it's close. This movie had a few riddles in it, half the type you've heard a million times before and the other half being nonesensical. Like this old one:

When is a door not a door?
