A couple of big, beefy blokes that love nothing more than a good ol' fashioned spew. Speaking in Californian accents, the brothers vomit loudly, first appearing in Episode 45 saying things like 'wanna spew up with me bro?' and 'love to have a fuckin’ chuck up bro!', followed by 35 seconds of vomit sounds.
The following episode, Episode 46, is dedicated to apologising for the Chunder Brothers, including making the podcast itself the Grub of the Week for the sketch. Also in that episode is a more inclusive (and political) attempt at vomit humour; the Spew People.
The Chunder Brothers make their long-awaited return in Episode 99, also known as the GrubMart episode.
In Episode 51, Greg reveals that the Chunder Brothers fraternity was literal, saying they were actually brothers.
