Rivers should flow, not ooze.

In this one, Ian and Liv are joined once again by Liv's sister/Ian's cousin Alexa once again to talk about the Cuyahoga River Fire, which took place in 1969. Like the name implies, the northeast Ohio river catches fire because it was so heavily polluted by local industry. Local politicians tried to address the pollution and clean up the ecosystem, but they had an extremely uphill battle ahead of them.

If your water tastes like medicine, probably best not to drink it.

Also, Liv struggles with basic sentence structure. Alexa makes plans to win an award. Ian goes on a failed beer run.
