It can be tough, trying to enter a different world. On the latest episode of 'Rizzoli & Isles' (Mon., 10PM ET on TNT), the pair of detectives investigate a murder that takes place in a very upper-crusty, wealthy sort of place.

[Spoiler alert.]

The murder in question involves an extremely posh son of an upper-class Boston family. Now, Jane and Maura (played by Angie Harmon and Sasha Alexander) must mix with the rich folks in order to solve the case.

Sadly, Jane doesn't really know what she's doing. Hanging out with wealthy people is surprisingly complicated!

... For instance, when you have dinner with rich people, there are so many forks and utensils to use. Jane just tries to navigate a simple meal, but still, she messes up. She can't even manage to eat some fish without getting in trouble.
