I heart Birthday Cake.

A cake modeled after a top-shelf alcohol—is most appropriate for your 21^st birthday. Besides Patrón; Belvedeire, Tanqueray Silver, Johnnie Walker Blue Label, and Louis XIII de Rémy Martin would also suffice.

But a cookie cake with of picture of you looking like an drunk, fake Ray Ban wearing, bike racer before the start of a criterium, is equally appropriate.
