The giraffe. He was stuck in a refrigerator

*****

An old man is walking along a nature path, enjoying his last years on earth. A warning sign appears, warning about the dangerous man eating crocodiles in the river ahead. He gets to the river, to find out there is no bridge! He looks left, he looks right, but his feet are quite tired and he doesn't feel like looking for a bridge, log, or anything to get him across without going in the river. So, he removes his socks and shoes and walks across the dirty river.
Why didn't the crocodiles attack him?

They were still at the animal party.

*****

As the old man finally gets across, he becomes quite tired, and rests. He shouldn't have pushed himself so much, walking along such a long trail. When he gets up to continue, he dies suddenly. How did he die?

A box fell out of an airplane and killed him.
