How to get rid of unwanted grandmas?

Lately my grandmas really been bugging me! She smells like an old person and I don't think I can take it much longer. She's constantly making me get off my xbox live and exercise. She makes me the grossest foods like cucumber spaghetti and ketchup soup. She all ways hogs the tv and watches the worst shows such as the news and sex and the city sometimes forcing me to watch it with her.Some times even forces me to rub her gross feet! So I guess I'm asking how to get rid of her for GOOD!HELP!!!!
