not a "funny" but an unusual, in that I've never seen it before, at least not attached to the beer itself
the full recipe for that beer.
quite a few breweries will list ingredients on their website, a few will share their recipes for those who ask and BrewDog released their entire recipe catalog, but I've never seen a recipe attached to a beer
never heard of this brewery/beer, no idea if it's any good & didn't buy it
edit: google-fu identifies it as a Ballast Point creation

The point of it is to taste it and try to recreate it yourself. There are competitions around the country to see who's the closest.
