Louisiana has made the Marchex Institute's list of the top 5 most potty-mouthed states, but also grabbed a top 5 spot in its list of most courteous states.

Marchex's figures have Louisiana grabbing the no. 4 spot on the list of states most likely to swear like a sailor, as well the no. 4 spot on the list of most courteous states. Apparently, people in the Sportsman's Paradise can curse with the best of them, but also mind their Ps and Qs.

According to Marchex's data and research team, the results come from an examination of more than 600,000 phone calls from the past year. The calls were all between consumers and businesses. Where else are folks at their friendliest -- or most frustrated?
