In DXP #260 we debrief a bit about Jason’s time “in his cups” last week, after which we observe a scientific mystery regarding hair growth. We then delve into the theology behind speaking in tongues. (What is it? Why do Pentecostals do it? And are they really just cunning linguists?) We answer a caller’s question about parenting and losing your religion at the same time, and then embark on a new record for the amount of time spent talking about pig hearts. Biebers involve mortgage interest and last week’s bieber.
