This scene occurs on Jeff's second meeting in The Big Lebowski's ("TBL") study, in which TBL is contrite and about to ask Jeff's help.
Jeff asks if he can roll himself a joint.
TBL hands him a document to read.
Alternating between a Jeff's-eye view of the document and a facial shot as he reads, the joint appears twice in his hand and twice in his mouth, without ever showing the exchange.
Continuity should have caught this.
Either that or Jeff is both very fast and very consistent!
