Strong Bad Email
From Homestar Runner Wiki
Strong Bad's emails are the most frequently updated feature of the Homestar Runner website. They were originally a small feature introduced in 2001, in which Strong Bad would mock the spelling and grammar of those who wrote to him. Although the animations were initially brief, the responses gradually grew to establish numerous catchphrases and running gags, as well as spin-offs like Trogdor, 20X6, Teen Girl Squad, and even the main character Homsar. A typical Strong Bad Email will also include numerous Easter eggs and other hidden material.
