For the same reasons Mint Juleps are the perfect Derby refreshment, they make a great football beverage. A drink you sip slowly, letting the ice slowly melt and stretch your cocktail even further.  (It also provides a nice lasting buzz that will continue past the Sunday Night Game with Olbermann and Patrick and right into Entourage.)  Everyone has a mint julep recipe they prefer, but I like this one since it cuts down on the little leaves that might get stuck in your teeth.
