You probably, no i'm quite sure you wont understand why any of this is funny.
This is a website ok made by some people from Wales, an area in wales is Rhondda Cynon Taff, with the taff river, so the title, taff wars is a cross between taff and star wars.
They take things, i think they have done star wars ,terminator, rambo, maybe other programs, and take clips, and replace the original audio with homemade audio, and the reason it is funny is because the kind of things they say and the way they speak is how some people speak, it's funny because the pubs and stuff they mention are all pubs around here, and it is like making fun of how some people are, things like how some people say "like" at the end of every sentence or phrases like "now in a minute" and the culture of the bad mannered youth, so lots of swearing, but maybe some people will appreciate it.
