Wow! They actually went through with the wedding. Usually when a sitcom sets up a wedding it's always somehow called off at the last minute, unless it's a series finale. So it was a nice surprise to see them actually go through with it. Very curious to see how Howard does with married life next season now. Loved Sheldon's Klingon bits, too, and Leonard's little jabs at Penny about rejecting his proposal.
Sheldon: "Would you like some aloe vera? Because you just got burned."
