He stole George from his home and presumably family in Africa... From the first book:Originally Posted by evilvegan
I've always considered the man in the yellow hat creepy, even when I was small. What kind of man spends all of his time with a monkey? And how did he get George in the first place?
(wiki)"What a nice little monkey," [the man] thought. "I would like to take him home with me." He put his hat on the ground and, of course, George was curious. He came down from the tree to look at the large yellow hat... [George] picked it up and put it on.
The hat covered George's head. He couldn't see. The man picked him up quickly and popped him into a bag. George was caught.
[The picture accompanying this text depicts George in a sack, only his head visible, with a very surprised look on his face.]
The man with the big yellow hat put George into a little boat, and a sailor rowed them both across the water to a big ship. George was sad, but he was still a bit curious.
