Sheldon: As is the tradition, I have prepared a series of disrespectful jokes which generate humor at Howard's expense. Prepare to have your ribs tickled.
Howard, I always thought you'd be the last one of us to ever get married, because you are so short and unappealing. Am I right?
Let's see here. Oh, seriously though, Howard, you're actually one of the most intelligent people I know. And that's a zinger, because you're not.
I've always thought that you'd make someone a fine husband someday. Assuming you'd be able to get the parts, and develop the engineering skills to assemble them, which I don't see as likely. Ha-cha!
Okay, let me see here. Okay, kidding aside, Howard, you are a good friend. And I wish you nothing but happiness. Bazinga, I don't!
Sheldon: Double-zinga! I do!
Good luck following that.
