1oz Freshly Squeezed Lemon Juice
1/2oz Triple Sec [the cheap stuff is preferred here]
1 egg white
Add the egg white to an empty shaker, seal the shaker, and shake for 30 seconds.
Add all ingredients to the shaker and fill with ice.
Shake and repeat "I must not tell lies" enough times to let the message sink in.
Strain and pour into a chilled cocktail glass.
