Thanks for jogging my memory on something related....

When Vito went into hiding in New Hampshire, Tony was lamenting to Melfi about how Vito was a great earner and helped out tremendously when Tony was in the hospital. Melfi called BS on it and told Tony he had implied earlier that he had "millions of dollars" and questioned how the hospital stay could have cost so much. Tony stammered around some excuse, but the veneer was certainly off.
