Eh.
Most of these laws make sense. Cows being in the road is a traffic safety issue and could cause an accident. Divorces are outlawed because the UK is mostly a Christian (unsure what sect.) country. It's illegal to be "drunk" in bars/pubs because that can cause a public disturbance. "Drunk" is a relative term though, so there's probably a sub-section of that law defining what level of alcohol in your blood determines you're "drunk." But a lot of these are kind of funny, especially the whole egg thing.
