I only remember a little about the movie but I remember I loved it when I was little

It is about a barbarian coming to the present from the past and he stays with this rich white women
I remember that he was like amazed in stuff like light and he would flip the light switch saying on and off for a long time and had a short temper and this other scence when he was take a bath and there were bubbles all over th place and for some reason I remember a lot of pink and white stuff in her house but mostly pink and once again she was very rich lived in a big mansion

I own this movie. It was very funny. When I get home I'll give you the name. My mind just took a hike and I can't remember the title right now.

The title is called Just Visiting.

Here's a link to see if it's the same movie you are thinking about. This came out in 2001.
