Spider-man the laughingstock

While taking our morning walk, my son asked me, "Mommy, where does the spider web come out of the spider? Out of his mouth or out of his bottom?"
I said, "Well, out of a part of his bottom."
Without missing a beat he said, "But Spider-man shoots his web from his fingers. That's good because if it came out of his bottom, all the bad guys would do is just laugh at him!"

I don't know where he comes up with this stuff but it keeps me smiling!
