Cool pranks for Grandma?!

Cool pranks for Grandma?

I need to know some pranks I can pull on my grandma. She's turning 92 and I want to make her laugh. I need pranks that aren't lame I need really good ones. I don't care if they're mean. She has a good sense of humor.

I would try the door and bucket trick over the bathroom with a string at the bottom of it attached to the bottom that way it would not fall on her head and when the door closes it locks from the outside, take away the clothes except for a tutu and ballerina dress and when she comes out, take a memorable picture! It is really fun to do.
