Higher education can be a bitch: classes, homework, thesises -- or are those theses? Regardless, after a while it makes your brain hurt. Unless, of course, the degree you seek is a tequila Ph.D. from Tommy's, where 145 pure blue agave tequilas, the largest selection outside Mexico, make for a unique educational opportunity. After a mere 70 double shots, plus a written test, you too will be among the few, the proud, the doctors of agave. Bartenders might do well to include this on their résumés. Nuclear physicists and school bus drivers might not.
