Whats the funniest thing youve ever heard at a museum?

I was visiting a museum of natural history, and one of the exhibits was a collection of fossils. One of the fossils was a small, fossilized mammal, and as I was looking at it, I heard a funny noise. It sounded like the mammal was saying, "What the heck?"

I stopped and listened, and sure enough, the mammal was saying that. I couldn't help but laugh out loud. It was the funniest thing I had ever heard at a museum.
