This teaser episode previews the full members-only mailbag by sharing one complete listener question. Kelsey from Michigan writes in about her dislike of carbonated drinks and her specific grievance that lemonade is being made carbonated, which she considers an affront to non-carbonated-drink people. The hosts discuss their own relationships with carbonation, with Jesse declaring himself carbonation crazy and Hodgman sharing an anecdote about drinking Italian mineral water at bedtime that left him feeling bloated. Jennifer shares a story about running a lemonade stand with her six-year-old, which quickly became a solo operation, complicated further when her husband appeared with a SodaStream suggesting improvements. Hodgman mentions his daughter Grace who refuses all carbonation. The hosts agree that Kelsey has the right to dislike carbonation but suggest she bring her own preferred drinks to parties rather than expecting hosts to provide them. The teaser ends with a pitch for Maximum Fun membership.
