Hank Hill ChatBot

This is an instance of microsoft/DialoGPT-small trained on a tv show character, Hank Hill from King of The Hill. The data comes from a csv file that contains character lines from the first 5 seasons of the show. Updated some portion of the data to accurately show Hank's famous pronunciation of the word "what" with "hwhat". Chat with the model:

Issues

Occasionally the chatbot just responds with just multiple '!' characters. The chatbot frequently responds with "I'm not your buddy, pal" to uncomfortable/strange prompts/messages. Still working on a fix for those known issues.
