One thing that quite a lot of people get annoyed about is using "literally" to mean "figuratively". Fortunately, these Vikings know how to use the word correctly.
(Of course, they're not literally Vikings. They're really actors playing Vikings in Horrible Histories, but you knew that, didn't you?)
I'm off to York for a few days, and it just happens that the Viking Festival is on, so I might post some more Viking-related stuff.
