Looking for some advice/input on wedding speeches. Long story short, my father in law does not care for me. I also don't care for him (this is putting it lightly). My soon-to-be FIL has a very bold personality (also putting it lightly) and is quite outspoken and often times inappropriate/crude with sexual innuendos (in reference to myself and my fiance) and I am really concerned about him making a speech at our wedding. Even if we didn't invite him to make a speech or told him we were not having speeches, he would still make one. He's the kind of guy who does whatever tf he wants and doesn't care who gets hurt along the way. I am worried that he will say something that paints me in a bad light, which happens just in everyday conversation as it is. My fiance is great about coming to my defense and has tried so hard to diffuse the situation, but it is what it is. So how do I sensor, or preferably keep him from making a speech? Do I tell the DJ not to let him have the mic if he goes for it? I also thought about inviting him to make a speech during the small rehearsal dinner, that might work... but I don't want to open up pandora's box, because that might cause him to go ape sh*t about making a speech at the wedding and then snowball from there.
Advice/help please!
