Jimmy is still really pissed at Howard for cutting in on his and Molly's dance.
I would guess that Jimmy probably didn't care, but he must have gotten an EARFUL from Molly. The entire weekend was planned with the guests comfort and enjoyment in mind, with the exception of the ceremony, and the 20 minutes or so for dances....couple/father of bride/mother of groom...
The fact that Howard couldn't be "bored" and had to horn in for attention is simply despicable. The wedding dance is sacred to the bride.
I'm surprised Howard could control himself for her walk down the isle.
This is worst than anything his staff has done at receptions.
From the bride's point of view, what's worse....a loud drunken guest having fun? Or having your only wedding dance, where pictures are being taken of you and your new husband interrupted by a baffoon who couldn't let you have that moment?
