It really is - because not only is it hilarious, it also highlights just how difficult modern farming has become - razor thin margins, at the whims of the weather, dealing with vandlism from local youths with nothing better to do etc. etc.
When was farming not on razor thin margins at the whims of the weather? At least US history is full of sharecropping where the farmers barely making ends meet and those with enough capital to own their own small farms not doing much better. Some of those who owned a lot of land with sharecroppers managed to do ok though. It's similar today, except sharecropping has gone out of style, I think. Big farms and little farms are on very thin margins, but thin margins on a small farm mean Clarkson made like a hundred pounds or something after a year (probably ignoring his capital costs).
