It should be noted that TMBG have produced several puppet videos and one whole music video at Homestar Runner. The puppet videos were various clips of the John's playing music while Homestar sang. The music video was from the song Experimental Film.
TMBG is also the source of many of the jokes and oddities in the online game Kingdom of Loathing , and one of the key puzzles in the recent game events involved the song "Ana NG"
