As Charlie breaks into Sylvia's wedding, he removes his hat and holds on to it. Sylvia then throws her bouquet to him, and it's gone. A moment later, the hat is shown on a side table near some flowers. A little later, the placement of the flowers has changed.
Charlie and Joe ([link-nm0000069] and [link-nm0915536]) are in the bathroom, the phone rings, Charlie goes into the bedroom and switches on a light as it's dark, yet moments earlier it was light.
At Sylvia's wedding Charlie stands in doorway with his hat in his hands. As Sylvia walks past, she throws her bouquet to him, which he catches in both hands; his hat is then seen on a table.
Charlie comes out of the shower bone-dry with his hair perfectly combed and sprayed and towels off as if he's wet.
(at around 1h 30 mins) When Sylvia enters his apartment, Charlie does a quick introduction of Sylvia to Julie, he says, "Julie, you know Julie, don't ya?"
