Need help locating episode/clip

I remember a clip or ep where Matt was telling Shane about how Shamans used to blame mental illness in a tribe on a neighboring tribes shaman casting spells on them to cause schizophrenia, causing a shaman beef. Based on the visuals it was a pre Texas move episode, can’t remember if there was a guest or not.

If y’all can track this down and prove I didn’t dream this convo up I will hit you with the craziest top you’ve ever had.
