Should I be concerned? Joking or verbal abuse?

My husband was very irritable and anxious today. We were having a great day then he began saying to me, "Well if you had half a brain in your head......", "Are you sure you are sheltered or sheltered and stupid?", "If you ever do that again I will call the cops on you!" He said he would call the cops on me because I punched him in the arm twice while our kids were out of town. I have been telling him for almost a year and a half that I don't find making fun of someones intelligence funny and it is hurtful to my kids (his step-children) and I. (even if you view them as smart/intelligent) He continues to say these things. He won't stop, I have no one to turn to/ no way out, I didn't know what to do. He will not stop to listen and think over what I've said and ask himself if I might be right. He goes on and on in a way that he thinks is humorous. It makes him seem to me so simalar to a hyper child with Attention Deficit Hyper-active Disorder. I see it as a CONTROLLING, HYPER, BI-POLAR, MEAN HEARTED, I'M SUPERIOR COWARDLY RANT! Do you believe from the information provided that I was in the wrong?
