I am not into mixed drinks so I would recomend you get your self a bottle of GAMMEL DANSK. It is a bit pricey but it is also your B-day. If you do buy a bottle then drink it at room temp as shots or put a shot in some coffee, soada or any juice.
If you do not like the flavor then stick it in the freezer, when chiled it has no taste at all but gets you compleatly stoned. It also works well for a stomach flu ;)

If that is not an option then buy some jagermeister. Nice smoothe taste and does the job very well.
