Simpsons, The Easter Egg - Mobsters

In the episode of The Simpsons where Moe gets really close with Maggie, Fat Tony and the mobsters are standing outside Maggie's window after they put her to bed. Maggie's in her bed and you hear Fat Tony start talking. He says

"Okay boys, tonight i want you to whack the Castellaneta family."

And Dan Castellaneta as you should know is the Italian-American actor/voice of Homer!
