Bob Ducca was created and performed by comedian Seth Morris as a recurring character on the Comedy Bang Bang podcast hosted by Scott Aukerman. Introduced as Aukerman's ex stepfather, Ducca became known for long, mundane monologues listing his many ailments, doctors and alternative treatments. The character built a cult following among podcast listeners and returned for many episodes over the years. Short clips of his health updates later circulated as reaction sounds online, where his serious tone about dubious treatments made lines about illness and cures easy to reuse.
