The day went off without a hitch (aside from some understandable Sheldon quirks holding things up). 

Both families came to celebrate, putting aside their differences. Penny saved the day by keeping the mothers in line, and hurrying the bride and groom along when science distracted them. 

Mark Hamill was even there to officiate the ceremony, Howard's gift to Sheldon. 

Their vows were unexpectedly touching. You might even need a tissue.

"Sheldon, when I was a little girl I used to dream about my wedding. Then I stopped, because I thought that day would never come. Then I met you. I don't know what the future holds, but I know that I've never been happier than I am in this moment, marrying you." 

"Amy, I usually know exactly what to say, but in this moment I have no words. I guess I'm overwhelmed by you, in a good way. Even if I can't tell you know how I feel, I will spend my life showing you how much I love you." 

Congratulations Sheldon and Amy!
