Lestraud leaves the bust of his career to help Holmes... who is trying to write a Best Man's Speech.

I thought the drunk part went on a little long but the drunk Sherlockisms made me laugh, like the chair being called an "Egg shaped sitty thing"

I also thought Molly had some fun reactions to everything and I really liked the Mary/Sherlock relationship. It felt like a different show, far closer to a sit-com but I loved it.

It was kind of a standalone episode but I think it was more to establish Mary's character so she can be in peril in the third episode when the shit hits the fan. Also, last season's 2nd episode (Hound of the Baskerville) was pretty standalone as well. And I think season 1 only tied in to Moriarty at the very end.
