A bunch of Brits getting all sweary in the early 20th Century. And yes, I do mean sweary. Also, there's a naked arse in the trailer, so you might want to be careful where you watch it. Notice that I posted that warning after the trailer, because that's the kind of wankerism such a trailer calls for. If you haven't already watched it, do so and you'll understand.
It is an english bum so it is really not sexual. I would not say the funniest of the year as I still have cramps from the opening of godzilla where he flattens two people in white coats and the effects were really good. It would have been a bit better if one of them had stuck to his tail and fallen off as it went back up, but pretty damned good since I was rooting for the G. However, this looks like uptight people swearing which really doesn't entertain me much. I have the internet so I have seen the "naughty" Things and then some. But to each their own and enjoy as you will.
