Grandpa Shithead

Grandpa Shithead is the father of Mrs Shithead and the grandfather of Colin Shithead and Kimberly Shithead.

History
Grandpa Shithead was estranged from his family and was last with his family when Colin was taken to court back in high school. He later reunited with Colin when he was staying at the Atlanta Paradise Motel with Luke Edwards. He later went back to Colin's hotel room with his grandson and met Luke. Unfortunately, Luke was on the toilet and asked for privacy, which infuriated him. Colin realized that Grandpa Shithead was really a dangerous man and was estranged from his family for a reason. When the police came to arrest Colin and Luke for blowing up a city, Colin blamed the destruction on his grandfather and his grandfather was subsequently arrested and imprisoned.
