Booze: "The lube of life"

I found one of those weird oil and vinegar bottles for $1 at a garage sale this weekend (not exactly like this one pictured here, but you get the idea), and asked the husband to write one of his notorious booze posts about the ideal kind of drink to serve in such a device. He says he needs a day to "brain on it." I suggested that you could possibly do a depth-charge type of drink, you know, isn't that the thing where you drop the shot glass of some type of booze into a beer or something? Or maybe a separated gin and tonic? I don't know, I've never been a very accomplished drinker. Anyone have any suggestions?
