Ring of Fire - S1.E5

Beth joins a mommy group and plans to make a good impression on the other mothers, but her hopes are dashed when the mothers tune in to The Jimmy and Carl Show on the day Kevin lights a ""zorch"" on air. This leads a group of college listeners to having a ""zorch contest"" (lighting their own gas on fire) which results in a bunch of guys in the ER with ""singed sphincters,"" so a guilt-ridden Jimmy sets out to ""rectify"" the situation.
