I know very little about nuclear physics. I know nothing about gay sex. I don't understand this explosion of different genders. I don't understand why the missus can't put socks together when they come out the washer or at least just leave it for me to do.
Its a long list.
The only thing I can claim with a massive degree of confidence, is that I know more about the performance of football managers than Groot. I also know ACS is whining softie. There is nothing wrong with the toilets in SJP. I use them regularly and they are very clean and modern.
