Other mistake: Barney asks the new bride to put Vinnie back on the phone, and she did. At that time she only knew Vinnie as Todd. (01:05:37)

Deliberate mistake: After the first scene where Hannah's ex-husband walks in without knocking and picks up the kids, Hannah is looking at some family pictures including her, her ex-husband, and the kids (supposedly taken when they were still married). But in the pictures they're all wearing the exact same clothes that they were in the previous scene. Could be a coincidence but that seems doubtful.
Vincent 'Vinnie' Antonelli: Ehh, she's not my type. I like 'em... I dunno, kinda dirty or something.
