Q: "Your uncle is living in the wrong century, and New York knows it."

A: Johnny Sack to Tony on Tony and Carmela's anniversary

This is incorrect. It wasn't Johnny Sack.

Q: In the meantime you leave comleigh (sp) trucking and anything else that belongs to uncle junior, including his haemarroid donut, the fuck alone!

A: Tony to Richie Aprile, second season.

This is partially incorrect. It WAS Tony, but he wasn't speaking to Richie Aprile. It was someone else.

Q: You better lamb-chop it for a while.

The answer to this is Furio, speaking to Tony about skipping town to avoid a murder charge for the death of Matthew Bevilaqua.

These two questions still stand:
Q: "Your uncle is living in the wrong century, and New York knows it."
and
Q: "In the meantime, you leave Comley Trucking and anything else that belongs to Uncle Junior, including his hemorrhoid donut, the fuck alone!"
