Half-full, why do you ask?

As the groom was walking down the aisle of the church to take his place at the altar, the best man and the maid of honor notice that he has a pretty contented smile on his face. Smiling back, the best man asked, "I know you're happy to be getting married, but aren't you a just little bit nervous?"

"Well," the groom replies, "it's not that. To tell you the truth, I just had the best blow job I have ever had in my entire life!"

Looking over they see the bride walking down the aisle and she, too, has a pretty contented smile on her face. The maid of honor smiles back, and ask, "So, and why are you so happy?"

"Well," the bride replies, "you see, I have just given the last blow job of my entire life."
