My vote from college days when I worked in California is Lucky vodka, sold next to the lettuce in Lucky grocery stores! For someone from state-controlled liquor sales in ABC stores, this was remarkable!!! The fake ID back at NCSU worked for Popov and some Canadian Mist for the freshman coeds! ^

BTW, it is typically Mezcal that had the worm (actually a larva), not Tequila. Still have a bottle from 1980 I got in TJ somewhere in the house.
