When bars have "you-call-it" specials, what are the best drinks to order (to take advantage of the deal)?

So I just got into medical school, and really need to go out and celebrate. Where I'm going tonight, they're having a you-call-it night, so I'm pumped to try new stuff. I don't go out too much... but when I do, I like random cool drinks, like Dirty Girl Scouts, and the Incredible Hulk (Hennessey and Hypnotiq), more so than the ole regulars like Screwdrivers and on the Beach. What would otherwise cost a lot of money, that I should order on a $2 drinks night, to make use of the special price?? Thanks for any input you guys can give me!! =)
