Bayou Self Cocktail

I found this online somewhere and intend to try it soon. It's highly rated on the website.

Pour captain morgan spiced rum , butterscotch schnapps and pineapple juice into a cocktail shaker half-filled with ice cubes.

Shake well , and strain into a highball glass 3 / 4 filled with ice.

Top with grenadine , and garnish with a maraschino cherry and a slice of pineapple.
