The best and worst TV weddings, from 'Downton Abbey' to 'The Office'

"Friends" delivered several memorable weddings over the years -- Ross' slip of the tongue with Emily, his and Rachel's hilarious, drunken Vegas nuptials ("Hello, Mrs. Ross!" "Hello, Mr. Rachel!"), Phoebe and Mike's snowbound ceremony -- but Monica (Courteney Cox) and Chandler's (Matthew Perry) stands out for how managed to come off (mostly) as intended despite all the turmoil swirling around it.
