Should Paternity Test Be Mandatory ?

We all have seen the shows where they pull out the envelop to see if the man's the father or not. The woman swear he is, she's 1000% and never slept with no one else. Then the host says ,"Chis you are not the father". This situation to me is not a laughing matter even tho shows have become popular off the matter. Me and my co-host Mr. Mango when give our thoughts.
