The dirty-car hypothetical, mohawks, and reaching across generations

• What legitimately causes your brother to stumble — and where is the line?

A host poses the hypothetical of an effective witness who then gets into a filthy 1986 Pinto with fried chicken and a cat — can extreme slovenliness legitimately make someone stumble? A host recalls his first church, where simply showing up bathed impressed people after a predecessor's filthy parsonage. They debate whether to evaluate a stumbling block against the whole population: a mohawk may repel a 60-year-old but open doors with punks, and different people reach different crowds, illustrated by Danielle reaching teens the older hosts can't, plus a detour through dreams about Jim Neighbors and the Andersons playing basketball.
