Explanation
Experiment
The joke plays on the idea of a grandparent, a symbol of innocence and guidance, being described as rusty. This is unexpected and unsettling, suggesting an inappropriate sexual connotation that would be considered taboo and shocking in the context of family. The punchline implies that she is still capable in a way that would be inappropriate in this context.
