The Incredible Hulk and his Elastic Purple Pants

How does the Incredible Hulk’s purple pants stay on?

No, really. Haven’t you thought to ask that before? Ever since I read the first comic versions of The Incredible Hulk, I always wondered how his pants can grow to size.

Here are some theories floating around.

My own theory? The pants are organic. They grow to accommodate The Hulk/Bruce Banner transformations. But material aside, Bruce Banner has very bad taste in underwear! Who wears purple?!
