Scorsese uses the gawky waiter's chilling double confrontation with Tommy as a revisit of the iconic 'Funny, how?' scene, illustrating how Tommy becomes more unhinged and reckless as the movie progresses.

First time, Spider gets the "Dance, motherfucker!" treatment and takes a bullet in the foot.

Second, he critically misreads Tommy's jokes about the foot bandage and talks back, provoking Tommy to aim higher.

And yes. Christopher from The Sopranos.
