He first appeared in "Mr. Hankey, the Christmas Poo" in the background at the South Park Elementary Christmas play. He later appeared in "Damien" at the bar with Mr. Allen, calling Jesus Christ "gay" in the style of their sons' catchphrase. He appears to share the exact same characteristics as his son, with the exception of the purple shirt; he wears a turquoise shirt which resembles that of Bill Allen's.
His appearance is pretty much the same as his son's, the only differences being height and the shirt; he wears a turquoise shirt rather than a purple one.
Much like his son, he likes to call things "gay" whilst laughing in a deep voice.
