That's Good Stuff
From Homestar Runner Wiki
"That's good stuff" is a phrase that shows up occasionally throughout the course of Homestar Runner, first appearing in the email environment, and later called back in Hremail 7. It usually includes two coughs (or, in Strong Bad's case, a laugh) before the line is said.
- Email environment — A flower chokingly utters this phrase after having recycled cigarette butts dumped on it.
- Strong Badia the Free Cave Girl Squad — Strong Bad says this if all four members of Teen Girl Squad die major deaths.
- Hremail 7 — Homestar Runner says this after choking on Melonade Throat Closers in a scene similar to the one in environment.
