Getting drank

Beavertown Brewery currently have these billboard adverts up, with the slogan Out of this world beer. Drank on Earth:

The verb drink is one of our irregular verbs, as it doesn't have a past tense of drinked, adding the regular past tense ending -ed, and instead changes its vowel, so you say I drank beer not I drinked beer. It also does this for the participle, which is what you use for various things including perfect aspect (I have drunk beer) and passive (The beer was drunk by me). This passive participle is also the one we use for things like relative clauses (The beer that is drunk on Earth). 

But there is variation! Not everyone has all three of these forms in all contexts. For a lot of people, drank is used for all the non-present forms (I drank the beer, I have drank the beer), while for others, drunk is used (I drunk the beer, I have drunk the beer). For everyone, the adjective is drunk, though (no one says I am drank!), which I think is a nice indication that it's somehow separate from the verb. 

In formal English, then, this slogan would say Out of this world beer, drunk on Earth, because it's the relative clause type: this is short for which is drunk on Earth. They've chosen instead to go with the form used in more informal contexts and said Drank on Earth. The company's image is very informal and friendly, so they presumably felt it fit more with that vibe, and it has the added benefit of not being mistaken for the adjective which might imply getting drunk, not a good look from the point of view of the advertising standards people. 

It wasn't then, but it was now

Linguists are liable to stop mid-conversation to write down something they or their interlocutor said, if it was linguistically interesting. Out for drinks with colleagues, the following happened. 

David, picking up a nearly-empty beer: Is this mine? 

*David downs the last of the beer*

Me: Well, it was now! 

And at this point we stopped to reflect on the fact that you really can't say that, unless you're a linguist mucking about with language for funnies. 

Now is a flexible sort of thing. It doesn't only mean this precise moment (which can be measured in infinitesimally smaller moments anyway). It can be the present time give or take a few minutes, or a few hours: 

I'm busy right now; I'll call you back when I'm finished. 

Or the present time give or take a few days: 

The delivery is due around now, I think. 

It can be the present time, probably extending into the future, since some past causal event or just compared to before: 

We have to submit form 3A now to claim expenses, not form 3B (since the new manager updated the policy). 

We generally have better living conditions now (compared to in the last century), though there are still too many people living in poverty.  

My now was, I think, a present situation resulting from a causal event, where since David had downed the pint, it was now (and forever, I suppose), his. If the beer wasn't his before, It is now. 

But as I said my line, I mentally switched it from It is now. Because the beer no longer existed, I changed the tense from present (is) to past (was). I left the temporal adverbial now untouched, however, thereby creating a weird mismatch between past time (the tense of the verb expressing the existence of the beer) and present time (the adverbial expressing the time that the state of affairs described pertains to). 

This is why we have things like present perfect and past perfect, that you might have studied at school: I have drunk the beer is present (state of affairs) and perfect (action completed in the past), so although the beer is already drunk, I'm describing the present situation. I had drunk the beer is about a completed action and a past state of affairs – the situation that I'm describing, in which the beer had already been drunk, was at some past time. 

I was, in effect, trying to make now cover both the present time (our current situation) and a past time (when the beer existed). Now can easily include some time in the past, like all of the past time since the new manager changed the policy in the example above, but crucially it has to be conceptualised as not being in a distinct past time. It has to be a single now period compared to a before period (or then, or whatever). So it has to be present tense for a current state of affairs. 

And lastly, the reason my line was a dorky linguist joke rather than an incomprehensible failure of tenses is that the phrase It is now! has become a set phrase or 'chunk' of language. I wasn't consciously referencing the commentary of the 1966 football world cup final, but this is an extremely well-known use of the phrase and I think it has got into people's vocabulary, including mine, as an idiomatic expression. It highlights the inevitability of the current situation, the sense of having pinched a victory, and the impossibility of having the outcome reversed.
