Series 1 Episode 10
S1 E10:
The band members begin doing charity work - including adopting a son in order to write-off as much of the money they've earned over the year as possible. The band's parenting consists of tying the boy outside, feeding him nothing but sugar and not providing him with a bathroom. They eventually release him back into the wild on an island overrun with bloodthirsty cats.
