I like the clever references to mob movies,
particularly to Goodfellas. Christopher Imperioli
who played Spider in Goodfellas and plays Chris Molitisanti in the Sopranos is a fantastic actor.
Two references to Goodfellas come to mind.

********SPOILIER********SPOILER*********SPOILER
1.
When Chris stops off to get some pastries for the
guys at the bakery and the serving guy lets
someone jump him in the queue. Chris is
seriously pissed off.
"Do I look like a p*ssy to you!!!!"
So angry that he has to shoot the guy in the foot.
"Next time you see my face - show some respect"


Of course it echoes the Goodfellas incident when
Tommy shoots Spider in the foot. It was a huge pleasure to see that Sopranos scene for the first time - with the memory of Spider.

Had me chuckling for a while!!
Fantastic irony that Chris Moltisanti is a self confessed Joe Pesci diehard fan.

2.
Chris is having nightmares that he f*cked up clipping Emil (E-mail) Colon. He decides to dig the body up to check. Having established that the guy is dead - though he now has a beard and women's fingernails, Chris decides to move the stiff to a new resting place. The words he use
beautifully remind us of digging up Billy Batts' body in Goodfellas following Jimmy's info about
condominiums and "having to get it out of there"

Chris Moltisanti:
"Help me lift him, we'll take him down the pine barrens before they build a f*cking condo here"

Genius writing. Absolute genius.
