Yep, That’s a Giant Peg in the Park
We really don’t know how people get themselves in certain situations sometimes. We only know that there are certain encounters at the park that can only be explained by the people involved, like this man, for instance.
He found a huge peg and somehow got his leg caught in it. He’s the only one that can explain how that happened. His dog on the other hand decided to remain an onlooker, watching him wail from the pain. Hopefully, he got help quickly otherwise, his leg may have suffered quite a bit.
