Things got ugly inside an Iowa City McDonald's restaurant over the weekend. It started out as a loud argument, and then quickly turned violent. Just watch this.

NOTE: The first video is VERY violent.

Here's another angle of the craziness that could have easily been inside an MMA ring.

The "discussion" certainly appears to include something to do with hair. Then, when the drink flies, it escalates real quick. The altercation happened over the weekend inside the McDonald's restaurant at 804 South Riverside Drive in Iowa City.

I certainly hope no one was injured in this crazy skirmish and what to do as a customer? If you listen closely to the end of the first video, you can hear someone say "I'm just tryin' to get some food." I'm guessing he had a bit of a wait on this particular occasion.
