Old Fashioned

2 parts American whiskey
1 part simple syrup
1-3 dashes Angostura bitters

Twist of lemon peel over the top, and serve garnished with the lemon peel and a maraschino cherry.

Note: There really isn't an alternative here. If you don't feel like muddling or peeling a lemon, just drink neat whiskey. Don Draper will still approve.
