No, Al. I think someone named the wrong liquor or else was teasing. Vodka should not smell like fish. I googled to make sure.

A long time ago, Smirnoff (I think) had an ad campaign which said "It leaves you breathless," implying that if you drink their vodka, people will not smell the alcohol on your breath. But take it from a non-drinker, when someone has been drinking vodka, I can tell by the smell. Apparently what I smell is not the alcohol itself but some other component. The smell seems like a solvent, not like fish.
