Werner is a German comic character created by Rötger Feldmann, a foul-mouthed biker and plumber whose adventures became hugely popular comics and animated films in Germany. Das muss kesseln became his signature catchphrase, even giving its name to one of the Werner films, and it is still quoted by fans who grew up with the character. The line about Herr Günzelsen calling captures that world of workshops, bikes and chaotic mates, and soundboard users keep sharing it because the slang and delivery are instantly recognisable even outside the original story.
